Why the check light is on on the Lada Kalina: causes and methods of troubleshooting

Causes of malfunction

"Check Engine" - translated from English means "Check the engine." It is this system that many car owners are beginning to check. The problem may be in one of the eight or 16 clogged valves of the Lada Kalina engine, injectors or electronic control unit.

Let's look at the problems that can cause the ECU to light up the check engine light on the Kalina instrument panel in more detail.

Spark plug

The first thing you need to check is the spark plugs of the Lada Kalina. It is advisable to carry out testing on a special spark plug stand. If it is not there, then the check can be done in the old-fashioned way.

There are two old-fashioned methods for checking spark plugs on a Lada Kalina. The first is to do the following:

1. Start the Kalina engine and remember how the engine works.
2. Disconnect the wires one at a time going to the breaker-distributor.
3. Listen to the motor running after each wire removal. If it remains the same on some spark plug, then this particular device needs to be removed and cleaned or replaced.

There is a second way to check, if the Kalina car owner is absolutely sure that the check light is on on the Lada due to the spark plugs.

1. Start the Kalina engine and remove the spark plug.
2. Bring it to the cylinder block.

Attention! Now don't be scared. The spark will be unexpectedly large if the element is alive. If Kalina’s candle is not working, then nothing will happen.

Experienced mechanics recommend checking the spark plugs of the Kalina engine on a special stand using a gun. The reliability of old-fashioned methods is not always correct.

Ignition coil

If the check light on the Kalina panel lights up, the car owner has checked the spark plugs and everything is fine with them, then the ignition coil will need to be tested. Its malfunction can also cause the check light on the Kalina instrument panel to light up.

The check is carried out as follows:

1. Replace the tip of the spark plug of the first cylinder of the Kalina engine with a previously prepared one. First check the functionality of the high-voltage wires with a multimeter.
2. Start the Kalina engine.

Now notice the spark. If the coil is working properly, a spark will appear between the electrodes. When the new coil is running, the spark is bright purple. If the color of the spark is yellow and it burns weakly, then this means that the coil has problems. It is advisable to replace it.

Catalyst

This device serves to reduce harm to nature when the Kalina engine is running. The catalyst destroys exhaust gases.

Problems with the oxygen sensor on Kalina cause catalytic converter failure. This device may burst due to the accumulation of exhaust gases inside the device. Then a check appears on Kalina. The reason for this failure is Kalina's high mileage. In addition to the hundreds of thousands of kilometers traveled, the cause of the failure may be low-quality fuel or old spark plugs.

Determined by a drop in engine power. Kalina loses dynamics during acceleration. It is recommended to replace the catalyst immediately so as not to completely repair the Kalina engine later.

Oxygen sensor

A lit check for Kalina indicates a malfunction in the oxygen sensor. Experienced mechanics call it a lambda probe. Usually a message appears on the instrument panel indicating that it is clogged, and the check light is on.

It is not recommended to clean it yourself, trying to save money. A faulty oxygen sensor will lead to breakdown of the catalyst and lead to several other problems. Therefore, the money saved will be a harbinger of greater costs.

Experienced car owners simply change the oxygen sensor on the Kalina engine when it fails.

Mass air flow sensor

Another reason why the check light is on on Kalina is a malfunction of the mass air flow sensor. The Kalina car owner will identify this breakdown by increasing fuel consumption. And the release of oxygen oxide when the mass air flow sensor is faulty leads to a decrease in the power of the machine. The smooth running of the vehicle is lost.

In winter or on cold autumn mornings, the car may not start right away. The mass air flow sensor breaks down due to the air filter being replaced at the wrong time, or due to improper installation by inexperienced craftsmen.

The mass air flow sensor on Kalina can be replaced independently. The cost of a new device is not high. But it does not greatly affect the performance of the engine in the future. But experienced mechanics recommend that all problems that appear with the Kalina engine and are related to the check be solved as they arise.

Wiring

When the check light on Kalina comes on, you must first carefully examine the high-voltage wires. They are the first in line to fix an illuminated Check Engine Light.

You will need to measure the resistance using a tester. The unit of resistance that is required for normal operation of the wires can be found in the Kalina engine operating book.

Even a novice Kalina driver can check and replace the wires. Therefore, this breakdown does not require service. But, if the car owner is not confident in himself and his abilities, then it is better to contact a car service center.

ECU

The reasons for the lighted check lie in the broken electronic unit of the Kalina engine. There may be a large number of accumulated problems in the ECU that cannot be reset on their own. Therefore, mechanics advise contacting a service station.

Lost firmware will also cause the check light to come on on Kalina. To determine them yourself, you need to connect the laptop to the ECU and open special software. The software will show the numerical values ​​of the faults.

In the table, the car owner will find a decoding of some numerical error values.

Attention! If you don’t know how to operate the software, it is better to contact experienced mechanics at an auto center.

Elimination of uneven motor operation

Most often, the engine stalls after washing due to water getting into the ignition system. This is where you should start troubleshooting. The following items need to be checked:

• distributor, if present in the ignition system;
• armored wires;
• ignition coil;
• candle wells.

If there is liquid on any of the above elements, it must be removed. When wiping elements, you should visually check their technical condition. There may be situations when, after washing, cracked high-voltage wires or worn-out spark plugs are revealed. If you notice an element that has come out of order, you must replace it without waiting for scheduled maintenance.

It is more difficult to detect water getting inside the cylinders and damage to the sensors. Usually in this case computer diagnostics comes to the rescue. By reading the error log, a specialist can determine why the Check Engine light came on and the engine tripped.

Computer diagnostics

What to do if the viburnum check light comes on

If the driver sees a check on the panel of the Kalina car, it means that the engine ECU has received error information from one of the engine components. Using diagnostic equipment, it is necessary to check what kind of malfunction it is, find it and solve it by replacing or adjusting it.

To prevent a check from appearing on a Kalina vehicle, the car owner must appear annually for preventive maintenance. Experienced mechanics will fix problems that the driver may not even be aware of.

where is the DDM light located and why is it on?

Checking the Priora oxygen sensor The Kalina oil pressure sensor is a fairly reliable device and rarely breaks down, but sometimes it fails. The article is dedicated to this device: what it is, where it is located, how to check its serviceability. Instructions for replacement are provided.

What you need to know about DDM?

A modern car has a large amount of electronics installed, based on the readings of which the electronic control unit issues the appropriate commands. One such device is the oil pressure sensor (OPS).

Purpose and location

The purpose of the DDM is to monitor the oil level in the power unit; as soon as the amount of lubricant drops below the permissible level, the corresponding indicator light lights up on the instrument panel.

The operating principle can be described as follows. Lubricant is supplied to all components of the system under pressure. The system includes a DDM, inside of which there is a membrane indicated by arrow 4. If the pressure is low, then the membrane is not deformed, the contacts numbered 3 are closed and the lamp indicated by arrow 2 is on.

When the engine starts, the pressure increases, the membrane is deformed and acts on the pusher that is installed on it. In this case, the contacts open and the light goes out.

The DDM is located on the cylinder head on the right, when viewed in the direction of travel, on the back side of the engine. It receives power through a wire with a plastic terminal, which makes it easy to detect.

Diagnostic features

If the indicator on the dashboard is constantly on, you should first check the oil level using a dipstick and the condition of the oil filter. It is also necessary to check for oil stains on the power unit housing. If the level is normal, you should check the device itself. The simplest test option is to install a known-good device instead of the device being tested.

You don’t have to buy a new one, you can ask your neighbor in the garage. True, the sensor should be exactly the same. If, after installing a working device, the indicator stops lighting, then the removed one is faulty.

In addition, using a multimeter, the power supply to the device is checked to see if there is an open circuit. If you have a pressure gauge, you can check the oil pressure. To check, you need to screw the pressure gauge into the DDM seat and start the engine. At idle, the pressure value should be above 0.65 kgf/cm2.

If you don't have a pressure gauge, there is another way to check. To do this, the sensor is unscrewed, and then the starter is cranked without starting the engine. If, when the starter rotates, oil splashes from the seat of the removed device, we can conclude that the device is faulty.

What does a burning oil pressure light indicate?

If the DDM indicator light on the instrument panel is constantly on, this indicates that the Lada Kalina oil pressure sensor is broken or the circuit is broken.

If after diagnostics it turns out that the device is faulty, it must be replaced (the author of the video is Alexander Skripchenko).

It is recommended to unscrew the old device before purchasing and take it with you so as not to make a mistake when choosing a new one. To replace it, it is better to purchase an original or a high-quality analogue. You should not buy a cheap product trying to save money on it, since a low-quality product will quickly become unusable and will have to be replaced again. If the DDM pad is in poor condition, it is worth replacing it too.

Replacement instructions

To carry out the work, you need to prepare a key for “21”.

The replacement procedure consists of the following steps:

1. First you need to open the hood and remove the protective plastic cover from the power unit.
2. Having found the sensor on the cylinder head, you need to disconnect the power terminal from it by pressing the latches.
3. If necessary, check the power supply.
4. Next, using the key set to “21”, unscrew the old device. We check it for serviceability.
5. If the old device is faulty, screw a new sensor in its place.
6. We connect the terminal with the power wire to the device, and return the decorative motor cover to its place.
7. Let's start the engine. The light on the instrument panel should go out.

If everything works, the DDM replacement ends here.

How to reset a check on Kalina yourself

It is not recommended to reset errors yourself if the Lada Kalina check engine light is on. The error information will disappear. In a car service, if something happens to the engine after the reset, they will not be able to determine what kind of malfunction caused the engine to stop working. This means that you will have to completely disassemble the motor. It's an expensive endeavor.

However, if the car owner is sure that the wires were simply shorted after washing the car (this happens), then he can do the following at his own peril and risk:

1. Turn the ignition key, but do not start the engine.
2. Open the hood and remove the terminal from the positive terminal of the battery.
3. Wait about 5 or 10 minutes.
4. Reinstall the positive battery terminal. Close the hood.
5. Turn off the ignition and turn it on again. Now start the engine and get ready to start driving.

The check lamp should disappear from the panel.

Diagnostic process

Instrument panel with which you can perform diagnostics

So, diagnostic operations using the dashboard are not complicated and almost every Kalina car owner is able to cope with this on their own. Following the step-by-step instructions described below, you can carry out diagnostics on any generation of VAZ 1117-1119.

Now let's move directly to the process of performing diagnostic operations:

1. We reset the daily mileage indicator. For this purpose, there is a special button on the instrument cluster. Using the daily mileage button we reset the indicator
2. Do not release the button and turn to position I. Insert the key into the ignition and turn to position 1
3. If everything is done correctly, then all the arrows on the instrument cluster will begin to move from the initial position (zero indicators) to the final ones. Instrument arrows move from the beginning to the final control point
4. Using the button on the wiper switch handle, we switch the information screen.
5. First of all, the tachometer and sensors are checked for functionality.
6. In the second case, the software version will be displayed on the screen. Often, as practice shows, this is version 3.0 or 3.2. The instrument panel screen shows the software version (in this case UEr 3.0)
7. In the third case, error codes that are present in the ECU will appear. Errors received during the diagnostic process. There are 8 and 4 errors in photo 6.
8. Now let's decipher the errors that can pop up on the dashboard screen:

Decoding instrument panel readings

2

— the on-board network voltage exceeds the norm;3

- An error has been detected in the fuel level sensor.
Occurs if there is an open circuit in the sensor within 20 seconds. 4
- an error has occurred in the coolant temperature sensor.
Appears if an open circuit is detected within 30 seconds. 5
- an error has been detected in the outside temperature sensor in the car.
If there are no sensor readings within 20 seconds, “-C” appears); 6
- detected;
7
— emergency oil pressure;
8
- error or malfunction of the brake system;
9
- low battery charge;

E

— determination of an error in a data packet stored in EEPROM.

Now all that remains is to compare all the errors that popped up on the screen with those listed above.

Running self-diagnosis, reading error codes, erasing errors (check engine)

Hello, tell me how to reset the error: Before starting the engine, I disconnected the air flow sensor (the connector on the air filter cover), and then I forgot to connect it and started the engine, after which it shows an error on my panel - the Engine System Malfunction Warning Light (orange) came on. . I turned the sensor back on, but the icon did not go out. How can I reset this error? Thanks in advance for your answer

Try this: To check 1. Turn on the ignition (without starting the engine), count for 3 seconds. 2. Quickly (within 5 seconds) press the gas pedal all the way 5 times 3. Immediately after the last press (release the pedal completely), count 7 seconds. 4.Press the pedal all the way and hold it until the CHECK (MI indicator) starts flashing. 5.Release the pedal and read the codes

four series of 10 flashes code 0000 - no problems detected if, for example, code 0102 - looks like this: 10 flashes // 1 flash // 10 flash // 2 flash. // — pause after reading the last error, everything repeats in a circle until you turn off the ignition.

We erase the errors that we received during check 0. Before performing step 1, the ignition must be turned off for at least 10 seconds 1. Turn on the ignition (without starting the engine), count 3 seconds. 2. Quickly (within 5 seconds) press the gas pedal all the way 5 times 3. Immediately after the last press (release the pedal completely), count 7 seconds. 4. Press the gas pedal all the way and keep it pressed until the “check” blinks in four series of 10 flashes

If the check engine light comes on on the dashboard of a Lada Kalina with an 8-valve engine, this is a fairly common occurrence. The reasons for the appearance of such an alarm signal are different, and there are many of them and most owners have already become familiar with them. Many car owners are interested in the question of how to reset a check.

In our material we will try to determine the main factors affecting the activation of this lamp. To identify the causes, you can use the diagnostic service of the service center. It is also possible to determine the influencing factor in independent mode. And how to reset a check.

Replacing the device

Sooner or later, everything falls into disrepair, and the coolant sensor in the Lada Kalina also faces the same fate.

If any problem does occur, the device cannot be repaired; it is simply replaced. But don’t worry about this, this procedure is not complicated, it can be done independently, or you can turn to professionals for help.

If you are sure that the problem is still in the coolant sensor, proceed with replacement

. First you need to drain the coolant, then remove the air filter. Next, the plastic clip opens and the sensor harness connector is separated. After this, the element can be easily removed from the thermostat housing. Installing a new device occurs the other way around: the element is first screwed into place where it should be, and only then fixed with all the clamps. The latest thing is to replace the antifreeze.

Naturally, when performing actions, you must follow all safety rules and be careful not to harm your property or yourself. As you can see, the procedure is actually not complicated.

, but if after this, malfunctions are observed in the operation of the car, and the engine in particular, it is worth contacting a service station and completely checking other systems.

Failure of the fuel tank, failure of the neutralizer

When the check engine light comes on, the owner of a Lada Kalina with an 8-valve engine first of all aims to find faults directly in the engine. However, the reason can sometimes “lurk” elsewhere. The glow of the symbol is caused by a loss of tightness in the fuel circuit. Even a loose tank cap can cause this situation.

Depressurization of the system involves the penetration of an additional portion of air into the circuit. In this case, a symptom such as an increase in fuel consumption appears, and the correct functioning of the engine itself is also disrupted.

When the owner of a Lada Kalina does not detect any extraneous sounds in the engine or other deviations in its operation, but the lamp on the dashboard still continues to glow, then the first step is to make sure that the gas tank cap is tight. Quite often there are situations in which drivers, in a frantic rush, forget to check that the cap is correctly and securely seated after refueling.

If after such a check the lamp on the dashboard “refuses” to go out, then you need to continue searching for other reasons. What to do when the catalyst “announces” its malfunction? This important component of the exhaust system serves to neutralize the flow of exhaust gases. It is no secret that a huge number of substances harmful to the surrounding atmosphere accumulate in the exhaust system during engine operation. Due to the presence and functioning of the neutralizer, the level of their emissions is reduced significantly.

Among the main signs of a breakdown of the catalyst in Lada Kalina, 2 experts highlight the factor of reduced engine power. This also manifests itself in worsening dynamics.

As already noted, a common reason for the neutralizer to become unusable is the breakdown of the lambda probe in the Lada Kalina 2. Also, worn-out spark plugs can significantly shorten the “life” of the exhaust circuit element considered here.

As a result of the influence of these factors, a significant decrease in the effect of gas neutralization is observed. Oxides accumulate inside the component, which over time leads to overheating and the risk of catalyst destruction. Operating a car with such a breakdown is undesirable, since incorrect operation of the engine will not allow the unit to develop the declared characteristics. Over time, a neutralizer that has become unusable can cause damage to the power plant, so timely replacement of this component is a more rational and cheaper measure compared to engine overhaul. To replace it, you will need to contact a service center, since it is unlikely that you will be able to carry out the repair procedure yourself.

Let us remind you that the keys to a long service life of the neutralizer are:

• timely replacement of spark plugs;
• use of high-quality fuel;
• correct operation of the lambda probe.

Another factor if the check light is on is the failure of the sensor responsible for the mass flow of air sucked into the intake manifold. This malfunction is characterized by a decrease in the engine power level and the failure of the unit to start smoothly when cold.

Why can the mass air flow sensor fail? One of the reasons for this annoying situation is the untimely replacement of the filter element in the air intake circuit. The motor itself is unlikely to suffer from a faulty state of the sensor, other than the indicated loss of power parameter. However, the owner will refuel more, due to the increase in consumption provoked by this fact. The price of the mass air flow sensor is not exorbitant, so it is not advisable to delay replacement. The repair procedure itself is not difficult to perform. This can also be done at the service center during scheduled maintenance.
