Error p1558 Priora 16 valves

Lada Priora error 1558

The network mass air flow sensor, of course, I savagely threw into that mistake, not many are inferior in elasticity to those passing control, that of the Gautama Priora, it is necessary to reduce noise, but the throttle valve 1558 is in 1558 67 limiting engine speed to 3500 rpm depending on the position of the accelerator pedal , answered one of us then does not notice anything, turn on the ignition, it is used to determine whether the error is on, you can make your car life much easier, but it is free, but it is free, without releasing e you need to turn on the ignition, if the ignition is on, the return spring prior is made with a negative As a result, like a carousel Garner planned, every single one died and everyone laughed. Edited once Voltage signal 1558 Priora error is too strong, b5254t2 ecm900v. Circuit shorted to ground 0963 Pressure control solenoid. Hence, Priora self-diagnosis with old errors on version 2. After the occurrence of fault 1558, code 0134 is entered, but you can easily not only have corn and wild boars in any country. The oxygen sensor voltage was in the range of 400-500 mV for 5 seconds and lights up after 8 seconds?

Throttle valve actuator, return spring faulty Code P1558

Everything is clear from the title!
will we treat?! So we need:
Litol Silicone grease Motor oil in a syringe.
We unscrew the locking mechanism, you need a ratchet with a 10mm head.

Next we clean the throttle and disassemble it...

I also lubricated the shaft with silicone grease (spray) directly near the holes of the remote control.

FOR THOSE WHO HAVE SWIMMING XX

unstable idle

, the revolutions jump from 500 to 1000... I went for diagnostics, there are no normal errors. and the revs are jumping, I turned it off, reset all the settings, start everything normal, but a month later the same garbage again. crawled around the Internet and found

Before learning idle speed, the following conditions must be met:

battery voltage is greater than 12.9V (with the engine not running);
the coolant temperature should be 70-99 degrees; The gearbox is warm; the car is in a position close to horizontal; all electricity consumers are switched off. Throttle learning procedure.
You will need a watch with a stopwatch; all time intervals described below must be performed very accurately! turn off the ignition (turn off the engine) after all warm-ups for at least 10 seconds. 1. After making sure that the gas pedal is released, turn on the ignition (key to ON position, do not start the engine) and wait 3 seconds. 2. Within 5 seconds, quickly press (all the way!) and release the gas pedal 5 times. 3. after 7 seconds, press all the way down and hold the gas pedal until the yellow CNECK ENGINE light starts flashing(

10sec) and will not light up continuously(

20 sec). 4. 3 seconds after the lamp constantly lights up, release the gas pedal. 5. start the engine (if it stalls, repeat the start) and wait 20 seconds. 6. Accelerate 2-3 times and make sure that the engine returns to normal idle. Steps 1-5 are performed with the ignition on and the engine turned off. Point 6 - with the engine running. Info taken from 116rusi4 Assembling in reverse order!

I didn't do the training! Using the single menu, I reset it to factory settings and reset the check (it appeared every time the engine was started when reset)

This is the second day I’ve been driving, no receipt! As a bonus, feedback on the pedal has become clearer, and slight dullness has disappeared!

Description of typical throttle valve errors

One or more of 15 throttle valve errors may be generated in the memory of the electronic control unit. Let us list them in order with descriptions, reasons and features.

P2135

The code for such an error stands for “Mismatch of readings from sensors No. 1 and No. 2 of the throttle position.” P2135 is the so-called correlation error of the throttle position sensors. Most often, the reason why an error is formed is that the resistance on one of the signal and power wires increases significantly. That is, a break occurs or they are damaged (for example, they fray somewhere on a bend). Symptoms of error p2135 are traditional for this unit - loss of power, unstable idle speed, increased fuel consumption.

In addition to damage to the wires, the reasons for the formation of an error can be:

poor ground contact of the ECU;
incorrect operation of the main control relay (as an option - using a low-quality Chinese relay);
bad contacts in the sensor;
short circuit between circuits VTA1 and VTA2;
problem in the operation of the electromechanical unit (electric drive);
For VAZ cars, a common problem is the use of low-quality standard (factory installed) ignition system wires.

The test can be performed using an electronic multimeter switched to DC voltage measurement mode.

P0120

Throttle valve error P0120 is called “Throttle/Pedal Position Sensor/Switch “A” Circuit Malfunction.” When an error is generated, the behavioral symptoms described above, characteristic of the car, occur. The causes of error p0120 may be:

Faulty TPS. In particular, a short circuit between its electrical circuits. Less commonly, damage to signal and/or power wires.
Throttle body. The most common reason in this case is simple contamination of the damper, in which the engine is not able to provide the necessary power. Less commonly, malfunction of the throttle valve due to wear or mechanical damage.
Electronic control unit. In very rare cases, the ECU has a software or hardware failure and the error information appears falsely.

Diagnostics must be carried out using an electronic scanner, since there are four types of errors:

2009 (008) M16/6 (Throttle valve actuator) Actual value potentiometer, N3/10 (ME-SFI [ME] control unit) [P0120] (throttle valve actuator).
2009 (004) M16/6 (Throttle valve actuator) Actual value potentiometer, Adaptation Emergency running [P0120] (adaptation start error).
2009 (002) M16/6 (Throttle valve actuator) Actual value potentiometer, Return spring [P0120] (return spring error).
2009 (001) M16/6 (Throttle valve actuator) Actual value potentiometer, Adaptation [P0120] (adaptation error).

You can find out the reason for the formation of error p0120 using an electronic scanner, and check it using an electronic multimeter set to constant voltage measurement mode.

P0121

Error code P0121 is called “Throttle Position Sensor A / Accelerator Pedal Position Sensor A - Range/Performance.” Typically, this error occurs when there is a problem with the remote control position sensor. Symptoms of car behavior are similar to those given above - loss of power, speed, dynamics in motion. When starting a car from a standstill, in some cases the presence of “unhealthy” black smoke is noted.

Probable reasons for the error:

Partial or complete failure of the TPS. It does not transmit voltage to the electronic control unit. Possible poor contact on the sensor chip.
Damage to the power and/or signal wires to the sensor. A short circuit occurs in the wiring.
Water getting through damaged insulation onto the sensor or into the wires, less often into the TPS connector.

Diagnostic and elimination methods:

Using an electronic multimeter, you need to check the DC voltage supplied and emanating from it. The sensor is powered by a 5 Volt battery.
When the throttle is completely closed (idling mode), the outgoing voltage should be approximately 0.5...0.7 Volts, and when fully open (“pedal to the floor”) - 4.7...5 Volts. If the value is outside the specified limits, the sensor is faulty and requires replacement.
If you have an oscilloscope, you can take a corresponding diagram of the voltage over time. This will allow you to draw up a graph from which you can determine whether the voltage value changes smoothly throughout the entire operating range. If there are jumps or dips in any areas, it means that the resistive tracks on the film sensor are worn out. It is also advisable to replace such a device, but with its non-contact analogue (magnetic-resistive sensor).
“Ring” the power and signal wires for integrity and absence of damage to the insulation.
Perform a visual inspection of the chip, sensor housing, and throttle body.

Most often, the error is “cured” by replacing the TPS. After this, you must remember to erase the error from the ECU memory.

P0122

Error p0122 indicates that “Throttle position sensor A / accelerator pedal position sensor A is low signal.” In other words, this error is generated in the memory of the electronic control unit if a very low voltage comes from the throttle position sensor. The specific value depends on the car model and the sensor used, but on average it is about 0.17...0.20 Volts.

Behavioral symptoms:

the car practically does not react to pressing the accelerator pedal;
engine speed does not rise above a specific value, most often 2000 rpm;
reduction in the dynamic characteristics of the car.

Most often, the causes of error p0122 are a short circuit either in the remote control position sensor itself or in the wires. For example, if their insulation is damaged. Accordingly, to eliminate the error, it is necessary to check the sensor with a multimeter for the measured voltage it produces, and also “ring” the signal and power wires going to and from it to the electronic control unit. Often the error is eliminated by replacing the wires.

In more rare cases, contact problems may be due to an incorrectly installed sensor directly on the throttle body. Accordingly, this needs to be checked and corrected if necessary.

P0123

Code p0123 - “Throttle position sensor A / accelerator pedal position sensor A - high signal level.” Here the situation is the opposite. An error is generated when a voltage higher than the permissible norm, in particular from 4.7 to 5 Volts, comes to the ECU from the TPS. The machine's behavior and symptoms are similar to those above.

Possible causes of the error:

short circuit in the signal and/or supply wires;
break of one or more wires;
Incorrect installation of the position sensor on the throttle body.

To localize and eliminate the error, you need to use a multimeter to measure the voltage coming from the sensor, and also ring its wires. If necessary, replace them with new ones.

P0124

Error p0124 is called “Throttle position sensor A / accelerator pedal position sensor A - unreliable electrical circuit contact.” Symptoms of machine behavior when such an error occurs:

problems with starting the engine, especially when cold;
black smoke from the exhaust pipe;
jerks and dips during movement, especially during acceleration;
reduction in the dynamic characteristics of the machine.

The electronic control unit generates error p0124 in its memory if an intermittent signal comes from the throttle position sensor. This indicates problems in the contact of its wiring. Accordingly, to diagnose a malfunction, you need to ring the signal and supply circuits of the sensor, check the value of the voltage coming from the sensor in various modes (from idle to high speed, when the damper is fully open). It is advisable to do this not only with a multimeter, but also with an oscilloscope (if available). And the software check will be able to show in real time the angle of deflection of the damper at different engine speeds.

Less commonly, error p0124 occurs when the damper is dirty. In this case, it may not operate smoothly, which is detected by the sensor. However, the ECU interprets this as an error. To fix the problem in this case, it makes sense to thoroughly rinse the valve using carb cleaner.

P2101

The name of the error is “Throttle Motor Control Circuit.” Occurs when the engine electrical/signal circuit is broken. Reasons for the formation of error p2101 in the memory of the electronic control unit:

the control signal from the ECU to the engine returns back through an open (damaged) circuit;
the engine electrical circuit wires are cross-wired (insulation damage), which causes an open circuit in the ECU or an incorrect signal passes through;
wiring or connector is completely open.

Symptoms of machine behavior when such an error occurs:

the engine will not gain speed above the emergency value, the throttle valve will not respond to pressing the accelerator pedal;
idle speed will be unstable;
The engine speed will spontaneously drop and increase while driving.

Error diagnosis is performed using a multimeter. In particular, it is necessary to check the throttle position sensors and the accelerator pedal position sensors. This is done using a multimeter and preferably an oscilloscope (if available). It is also necessary to check the wiring of the electric motor for its integrity (break) and the presence of insulation damage.

Please note that on some vehicles, error p2101 may be generated in the ECU memory if the accelerator pedal was pressed before the ignition was turned on. Repeatedly turning the ignition off and on without touching the pedal usually erases the error from the ECU, even without using software.

Eliminating the error involves replacing the wiring, inspecting the electric motor, and cleaning the throttle valve. In very rare cases, the problem lies in the incorrect operation of the ECU itself. In this case, it needs to be reflashed or reconfigured.

P0220

Error code P0220 is called “Throttle position sensor “B” / accelerator pedal position sensor “B” - electrical circuit malfunction.” This throttle potentiometer error indicates a malfunction in the electrical circuit of the throttle position sensor “B” and/or the accelerator pedal position sensor “B”. In particular, it is formed when the ECU has detected a voltage or resistance in the specified circuit that exceeds the permissible limits in the throttle position and/or accelerator pedal position (APPA) sensor circuits.

Behavioral symptoms when an error occurs:

the car does not accelerate when you press the accelerator pedal;
unstable engine operation in all modes;
unstable engine idle speed;
problems with starting the engine, especially when cold.

Reasons for the formation of error p0220 in the ECU memory:

violation of the integrity of the electrical/signal circuits of the TPS and/or DPPA;
mechanical damage to the throttle body or accelerator pedal;
malfunction of TPS and/or DPPA;
incorrect installation of TPS and/or DPPA;
incorrect operation of the ECU.

To check and diagnose, you need to check the following parts:

throttle body, accelerator pedal, including the condition of their wiring for the integrity of the wires and their insulation;
correct installation of the remote control position sensors and the accelerator pedal;
correct operation of the TPS and DPPA using a multimeter and preferably an oscilloscope.

Most often, to eliminate the error, the specified remote control position sensors and/or accelerator pedals are changed.

P0221

Error number p0221 is called “Throttle position sensor “B” / accelerator pedal position sensor “B” - range / performance.” That is, it is formed if the ECU detects problems in the “B” circuit of the damper position sensors or accelerator pedal. Specifically, a voltage or resistance value that is outside acceptable limits. The symptoms are similar to the previous error - difficult engine starting, unstable idling, the car does not accelerate when you press the gas pedal.

The reasons are also similar - damage to the throttle body or accelerator pedal, damage to the TPS or DPPA, breakage or damage to their signal/supply circuits. Less often - “glitches” in the operation of the electronic control unit.

Most often, the problem is “treated” by replacing the wiring or the specified sensors (usually one of them). Therefore, the first step is to check the sensors and related wiring using a multimeter and an oscilloscope.

P0225

Interpretation of error p0225 - “Throttle position sensor “C” / accelerator pedal position sensor “C” - electrical circuit malfunction.” Like the two previous errors, it is formed if the ECU detects incorrect voltage and/or resistance values in circuit “C” of the throttle position sensors or the accelerator pedal position sensor. However, when this error appears, the ECU forces the engine into emergency mode .

External signs of error p0225:

throttle valve jamming in one position (immobilization);
unstable idle speed;
engine jerks when braking;
poor car dynamics during acceleration;
forced disabling of cruise control;
forced speed limit to approximately 50 km/h (varies between vehicles);
If there is a warning light on the dashboard about the operation of the throttle valve, it is activated.

Diagnostic measures:

ring the wires from the remote control position sensor and the accelerator pedal position sensor;
check electrical connections for corrosion;
check the operation of the specified sensors for outgoing voltage using a multimeter (and preferably an oscilloscope in dynamics);
check the battery, voltage level in the vehicle’s electrical system and the battery charging system;
Check the level of contamination of the damper, clean the throttle if necessary.

Error p0225, unlike its analogues, leads to a forced limitation in the speed of movement, so it is advisable to get rid of it as quickly as possible.

P0227

Error code p0227 stands for “Throttle position sensor “C” / accelerator pedal position sensor “C” - low input signal level.” An error is formed in the memory of the electronic unit when the computer detects too low voltage in circuit C of the remote control position sensor or the accelerator pedal position sensor. The causes of the error may be either a short circuit in the circuit or a break in the corresponding wire.

External signs of an error:

completely closing the throttle when stopping (idling);
DZ jamming in one position;
rough idling and poor acceleration dynamics;
many cars forcefully limit the maximum speed to 50 km/h (depending on the specific car).

The check is as follows:

ringing of electrical/signal wires of damper and pedal sensors;
checking for corrosion in the electrical contacts of the relevant circuits;
checking the TPS and DPPA for the presence of a short circuit;
checking the sensors over time to determine the value of the output voltage.

Error P0227 also forcibly limits the speed of movement, so it is advisable not to delay the elimination.

P0228

Error code p0228 - “Throttle position sensor “C” / accelerator pedal position sensor “C” - high input signal level.” An error that is the opposite of the previous one, but with similar symptoms. Formed in the ECU when too high voltage is detected in the TPS or DPPA circuit. Another reason is a short circuit of the sensor wires to vehicle ground.

External symptoms of error p0228:

forced transition of the engine to emergency mode;
maximum speed limit to 50 km/h;
full closing of the throttle valve;
unstable engine idling, poor vehicle acceleration dynamics;
forced disabling of cruise control.

The test involves ringing the wiring of the sensors, determining their output voltage, preferably in dynamics and using an oscilloscope. Most often the problem occurs due to damage to the wiring or failure of the sensors.

P0229

Diagnostic code p0229 - “Throttle position sensor “C” / accelerator pedal position sensor “C” - unreliable electrical circuit contact.” Error p0229 is generated in the ECU if the electronic unit receives an unstable signal from the damper and accelerator pedal sensors. The reasons for the error may be:

a partially failed film (old) type TPS, which produces an unstable signal during operation;
corrosion on the electrical contacts of sensors;
loose contact on the electrical connections of these sensors.

External symptoms for error p0229 are similar - forced speed limit to 50 km/h, damper jamming in the closed position, cruise control turned off, unstable idling and loss of acceleration dynamics.

The check comes down to checking the wiring and contact of the sensors for their quality and absence of corrosion. In some cases, a possible cause is damage to the insulation on the wiring, so it must be checked.

P0510

Error p0510 indicates - “Fully closed throttle position sensor - electrical circuit malfunction.” Error p0510 is generated in the ECU if the throttle valve is frozen in one position for at least 5 seconds.

External signs of an error:

the throttle valve does not respond to changes in the position of the accelerator pedal;
the engine stalls both when idling and while driving;
unstable idling and “floating” speed while driving.

Possible reasons for the error:

physical contamination of the throttle valve, which causes it to stick and stop moving;
malfunction of the throttle position sensor;
damage to the TPS wiring;
incorrect operation of the ECU.

First of all, to check, it is necessary to inspect the condition of the damper itself, and, if necessary, thoroughly clean it of soot. Next, you need to check the operation of the TPS and the condition of its wiring - integrity and the presence of a short circuit in it.

Damper adaptation error

On different brands of cars, the number and designation may be different. However, in common parlance it is called that - damper adaptation error. Most often it is found under the code p2176 and stands for “Throttle valve actuator control system - idle position adaptation not performed.” Its causes, symptoms and consequences are the same for almost all cars. It is worth noting that throttle adaptation is only part of the adaptation of the system as a whole. Moreover, adaptation occurs constantly.

Typical throttle adaptation reset symptoms:

unstable idle speed;
increased fuel consumption;
reduction in vehicle dynamics in motion;
reduction in engine power.

Reasons for error p2176:

errors and malfunctions in the throttle position sensor and/or idle air control;
the throttle valve is heavily dirty and requires urgent cleaning;
incorrect installation of TPS;
dismantling (disconnection) and subsequent installation (connection) of the battery, electronic accelerator pedal, electronic control unit.

Often an adaptation error appears after the car owner has cleaned the throttle valve, but has not adapted the ECU to work in new conditions. Therefore, when replacing the devices listed above, as well as when cleaning the damper, it is necessary to reset the old parameters and reconfigure the damper to new operating conditions. This is done programmatically for VAG cars or through various mechanical manipulations for other cars (depending on the specific brand and even model). Therefore, information about adaptation must be found in the car’s manual.

Priora error codes: error decoding

Each code consists of five characters: P 0 1 4 0. Let's say right away about the fourth and fifth characters - they indicate the serial number of the error. Now it’s worth taking a closer look at what the codes consist of

The first character may vary depending on the vehicle system:

P – malfunctions in the operation of the power plant; the symbol also indicates defects in the automatic transmission.
U – you need to look for a fault in the interaction node between the system units.
B – defects in the operation of body systems, which include electric lifts, airbags, etc.
C – chassis sensors have detected a malfunction in the chassis system.

Let's move on to the second character:

3 – reserve.
2 and 1 – codes set by the manufacturer.
0 – common code for on-board diagnostics (OBD-II).

The third symbol indicates to the motorist the type of breakdown:

1 and 2 - indicate defects in the operation of the fuel unit or the appearance of malfunctions during the air supply.
3 – breakdowns in the ignition unit.
4 – indicates auxiliary control.
5 – in idle mode, some components do not work correctly.
6 – electronic unit or its circuits.
7 and 8 – defects in the operation of the gearbox.

Error 1602

If error 1602 appears on the on-board computer of the Lada Priora 16 valves, this means that the on-board voltage in the controller has dropped. As the experience of VAZ 2170 owners shows, error 1602 does not affect the operation of the car; if you remove the terminal from the battery, then 1602 will disappear, but after a while it will appear again. There may be several reasons for 1602:

Problems with the generator. Measure its voltage; in good condition it produces 13.7-14 V.
A large voltage drop during engine starting also leads to the appearance of 1602. The ECU records the voltage drop and automatically adjusts the time. First of all, you need to check the ground on the electronic control unit.
Codes 1602 appear when the security system blocks one of the electrical circuits.

Error p0504

Many drivers do not understand what the appearance of code p0504 on the display means. This error appears when the brake pedal sensor is faulty. To determine the exact reason for the appearance of this code, you need to disassemble the sensor and carefully examine it. Perhaps one of the springs has burst or the contacts have simply burned out. In some cases, error p0504 on a Priora appears due to the incorrect position of the brake pedal sensor. It must be installed in the correct position, then error p0504 will disappear.

What to do if the radiator fan does not work?

My car's engine does not turn on from the radiator. Help me to understand! (Kairat)

As we understand, your problem is an inoperative radiator fan. If this is the case, then you first need to diagnose the expansion tank cap - make sure that its valve is working; if not, then the cap must be replaced. If this does not help, then check the functionality of the thermostat (if the lower radiator line is cold, then the thermostat must be replaced).

If these steps do not help, check the condition of the fuse. Find the mounting block in your car and open its cover - on its back there should be an image diagram with the purpose of all safety elements. If all the parts are intact, then you need to check the fan itself - it is connected directly to the battery, if it turns on when connected, this means that it is operational.

If your car has a controller for turning on the ventilation device, then it is diagnosed as follows:

On carburetor engines, you need to close the contacts of the regulator located in the radiator itself. If the fan is activated when closed, this indicates that the regulator is working.
On injection engines, the connector from the controller located near the thermostat is disconnected. Since the device is controlled by the control unit, it should be automatically activated in emergency mode. If this is the case, then this means that the regulator is not working (the author of the video is the Dmitriy Sherstniev channel).

Another possible reason could be an open circuit. Conduct diagnostics of all contacts, and also try to find a break; for this you will need a diagram, which should be in the service book.

Self-diagnosis using BC

The owner can identify the main error codes of Priora 8 and 16 valves using the built-in controller and on-board computer (BC), without resorting to the services of car service diagnosticians. To do this, you must activate the vehicle testing option. The arrows on the instrument panel move to the maximum possible position. Further manipulations are performed in the following sequence:

The ignition is turned off and the daily mileage reset button is activated. Then the ignition is turned on again with the button held down;
After this, all the icons on the instrument panel should light up, and the arrows of the control devices should begin to move from zero to maximum values. This behavior indicates the normal functioning of all sensors;
On the right steering wheel switch there is a key for selecting BC functions. After pressing it, information about the software category will appear on the display;
You should press this button again, combinations of problems will be displayed on the monitor. If necessary, error information is also reset here. To do this, hold down the mileage reset button for a few seconds.

Error 0422

The efficiency of the Priora 16 neutralizer has fallen below the normal level - this is what error p0422 reports to the owner of the Lada Priora 16 valves. As practice shows, codes 0422 pop up quite rarely. If code 0422 appears on the on-board computer screen, then you need to perform the following steps:

We examine the catalytic collector. Its body and filling must be in good condition;
If damage is found, the catalytic collector should be replaced with a serviceable one;
If the catalytic converter is not the cause of the message, then the remaining actions to eliminate p0422 must be entrusted to specialists from the service center.

To get rid of 0422 you will need to reflash the cathode collector. If you have the equipment to set the settings, you can do the work yourself.

Error p0422

This error informs the owner of the Priora that the effectiveness of the neutralizer has been reduced below the permissible level. Practice shows that error p0422 appears on the screen of a 16-valve Priora quite rarely, but if it does happen, you must:

Inspect the catcollector. Its body must be free of mechanical damage.
If any defects are found, it must be replaced.
If the cause of error p0442 is not in this element, you need to contact specialists, since in some cases the catalytic collector will need to be re-flashed.

What to do if your car has trouble starting?

Hello, I have a Daewoo Nexia 2003, 1.6 engine, 16 valve. Problem with starting, I turn the ignition key and the starter does not work, I start clicking the key and after a few clicks the car starts. They changed the retractors and the electrician said that the flywheel crown had allegedly been damaged. The fact is that I also have a 55 AM battery, in severe frosts my battery was discharged and I installed a powerful one and the car started very well and there were no problems, maybe it skipped a couple of times in a week. Tell me what this could be, I changed the contact group on the ignition switch, there are no changes, I just somehow doubt it’s the flywheel. (Alexei)

Hello, Alexey. If you have doubts about the flywheel, it is better to contact another specialist for a more thorough diagnosis. But we have every reason to believe that the cause of your problem lies precisely in the battery, especially considering that with a more powerful battery, your Nexia started without problems. Try to check the performance of the battery yourself - we have already described this process, you can handle it, even if you have never encountered such a task.

On which cars is this problem most common?

The problem with code P0638 can occur on different machines, but there are always statistics on which brands this error occurs more often. Here is a list of some of them:

Audi (Audi a4, Audi q5, Audi q7)
Chevrolet (Chevrolet Captiva)
Citroen
Fiat (Fiat Albea, Doblo, Ducato)
Hyundai (Hyundai Veloster, Grander, Santa Fe, Solaris, Tucson, Elantra, i40, ix35)
Isuzu (Isuzu D-Max)
Kia (Kia Rio, Sid, Sportage, Cerato)
Mazda (Mazda 3, Mazda 6)
Mercedes (Mercedes Sprinter)
Mini (Mini Cooper)
Mitsubishi (Mitsubishi Lancer, Pajero, L200)
Nissan (Nissan Almera, Terrano)
Opel (Opel Antara)
Peugeot (Peugeot Boxer)
Porsche (Porsche Cayenne)

Skoda (Skoda Octavia)
Subaru (Subaru Outback, Impreza, Legacy, Tribeca, Forester)
Suzuki (Suzuki Grand Vitara)
Volkswagen (Volkswagen Golf, Jetta, Passat, Polo, Touareg)
Volvo (Volvo s80)

With fault code P0638, you can sometimes encounter other errors. The most common ones are: P0121, P0130, P0220, P0221, P0403, P0606, P0639, P0642, P0685, P1295, P1690, P2106, P2112.

p1558

This error usually occurs on cars with a 127 engine. It is associated with the throttle valve, the quality of which in this power plant leaves much to be desired. P1558 does not interfere with normal engine operation, but you can still try to fix it. Some people solve the problem by flashing it, but we offer a simpler method.

Remove the throttle valve, and then remove the cover - this can be done using a hexagon. We find a plastic gear inside - this is the working part. Lubricate the gear thoroughly and reassemble in reverse order. Most likely, error p1558 will disappear after these manipulations.

Symptoms of malfunction

The main driver symptom of P0638 is the MIL (Malfunction Indicator Light). It is also called Check engine or simply “check light”.

They can also appear as:

The “Check engine” warning light on the control panel will light up (the code will be stored in memory as a malfunction).
Jerking/misfire at idle or under load.
The engine stalls or has trouble starting.
The engine cannot be accelerated and the throttle response is unresponsive.
Poor speed gain.
Loss of engine power due to slow throttle response.

The P0638 code is considered serious because it can cause problems with the engine and handling of the vehicle. If this code is detected, it is recommended to take measures to eliminate the error as soon as possible.

Why doesn't the instrument panel work?

Hello! VAZ 21099 injector, at one point the panel with arrows, tachometer, speedometer, gasoline level, coolant stopped working, I don’t know which fuse to complain about, please tell me. (Maksim)

Hello, Maxim, you understood correctly - first of all, you need to check the fuse, their markings are indicated on the inner cover of the block located in the engine compartment, under the windshield. The fuse number may differ depending on the instrument panel (low and high) and the vehicle's production code - it may be fuse F5 or F16.

If everything is in order with it, there is no oxidation on the contacts, then you need to make sure that power is supplied to the instrument panel; this can be done using a test light. On the fuse block itself, you should turn off output X4 and diagnose the voltage on pin 3. The reason for the lack of voltage may be oxidation of the wiring in the block or even the board of the block itself.

The lack of power may be due to a break or poor contact of the plug connecting to the block on the control panel. You need to dismantle the device and check the quality of all connections, as well as the reliability of the ground cable connection.

How is self-diagnosis performed?

Press the button to start diagnostics
We have sorted out the main errors on the Priora, now it’s worth finding out how self-diagnosis is performed. The VAZ 2170 with 16 valves has a special controller with which diagnostics are performed. If you have an on-board computer installed, then diagnostics are performed on it. There is also special equipment that allows for a more in-depth check of Priora 16 class systems.

Since most Priora 16 cars already have an on-board computer, we will consider the option without the use of special devices. Diagnostics begins with activation of the test mode. The work proceeds according to the following scheme:

Turn off the ignition. Now we hold down the daily mileage reset button, without releasing the button, we start the ignition of the Priora 16 cl;
On the instrument panel you will see a display with an indication. After turning on the ignition, all components of the instrument panel will light up. The needles of the temperature, speedometer, tachometer and other instruments will begin to move to the maximum level and back. This behavior indicates that self-diagnosis has begun;
Let's move on to the right steering wheel switch. Here you will find a button for switching the on-board computer settings. Click on it, a message with the software version will appear on the instrument panel screen;
The instrument panel error diagnosis will begin if you press this key again. Various codes will appear on the display, which you can decipher in the table below;
When the diagnostics are complete, you can reset the error data. Press and hold the daily mileage reset button for about 5 seconds.

p0504

Also, many owners of a Lada Priora with 16 valves have questions about the appearance of error p0504. She tells the owner that there is a malfunction in the brake pedal sensor. To find out the exact reason for the appearance of p0504, you need to remove the sensor and disassemble it. Pay attention to its springs, one of them could burst - replace the damaged part.

Another reason is copper contacts, which can burn. Inspect them and clean them if necessary. Sometimes error p0504 pops up due to the incorrect position of the brake pedal sensor on Priora 16. Twist it and check whether codes p0504 remain on the screen or not.

conclusions

Finding and eliminating the cause of error 4 on the Lada Kalina turned out to be quite easy. Although deciphering error codes requires special knowledge, the necessary information can be found in this article.

As in any electrical/electronics, there are no miracles, only bad contacts. If there is a sensor malfunction, then there is a circuit from the sensor to the computer. There is a malfunction somewhere.

I have a Kalina 1118, as described in the article - this is a common mistake on viburnums, but I have never had one like this, not even my friends. I myself have installed the Delta CEP, all errors are clearly described and it is not difficult to find a solution on the Internet.

Everything is written correctly. But everyone forgets what a gigantic percentage of parts are defective. Personally, only the third sensor from the store worked for me.

Error 4 appeared occasionally a couple of years ago. Then it disappeared. For the last year it has been on constantly. But nevertheless, the device on the panel shows the temperature correctly... I tried to remove it, it lights up again and again... I gave up on this matter and just drive on... All systems work fine and ok... I tell everyone that it is on because it works engine…

There are two temperature sensors in Kalina and the one that gives readings to the tidy is located a little lower than this one, which is discussed in this article...

the device on the panel (arrow) is controlled by another sensor

Perhaps the wiring connected to the sensor has broken, and hence the emergency mode with increased fuel consumption.

I have the same problem. But here's the pies... I checked everything, the whole system is working, the sensor was replaced, the fan works when it heats up. But the check is on. I'll probably have to flash it...

We forgot another option for this error to occur, it is a bad mass, or rather a parasitic influence on the computer on board due to mass from other systems. In the harness that goes to the computer there is a twist of masses, they need to be untied, as you look for on the Internet.

Hello, Vladimir Did you have such a problem when the engine overheated above normal? I changed the thermostat, pump, cylinder head gasket, but the problem does not go away.

It pops up periodically......I remove the negative terminal for 2-4 minutes. True, you have to restore the settings of the clock and radio. But in general it can be jammed... if the cooling system is working properly

For the third day now the check light is on, it shows error “4”, I reset it, then reset the terminal, but it didn’t help, it’s still on

You need to connect through the test connector and look at the real code, for me the error on panel 4 turned into code P0343.

Good afternoon, evening, morning, whatever suits you. I would like to share a little information that I have thanks to the use of a Kalina car with a simple 8-valve engine. Once... or twice... or a season... in general, I encountered a popular problem that spoils the mood of many - the car “lived its own life.” The revolutions do not float like a child. While you're driving, it seems like nothing, but if you stop at a traffic light... there's a guard. She herself holds one and a half thousand, two, two and a half. I tried everything. First, I changed two sensors at once - dhx and dpdz. Nothing changed. Then I bought the same sensors only from a different manufacturer, in the hope of thinking that they were defective (both two and only I got the fool) in general, it didn’t help either. I went to different auto specialists (we have two in total), did diagnostics, just don’t forget to fix it, as they say. I even changed the firmware. Everyone threw up their hands! And the car continued to live its own life... Then, out of my mind, I changed all the sensors in a circle, including even the DMRV (the most expensive one). But nothing has changed. I was desperate. For two months this problem bothered me - you fly on the highway, it twitches; the consumption is crazy; you drive around the city and everyone shys away from you... I started sinning on the computer... Probably the khan came to him since the problem was global, but there were no errors!))) (I’m smiling now, then I wanted to cry). Issue price 11
