Vesta clutch sensor: adjustment, what it’s for, where it’s located

Often Lada Vesta owners complain about knocking and jamming when moving from first to second gear. Shocks are less common when turning on third speed. The reason for this behavior of the transmission is wear of the clutch sensor, violation of the gaps, and an increase in the free play of the pedal.

It is quite possible to adjust the unit with your own hands; there is no need to go to a workshop. The exception is the current factory warranty for the technical product.

Replacing and checking the clutch pedal position sensor on Lada Vesta and XRAY

The clutch status signal is transmitted from the clutch switch. This signal allows the electronic engine control unit to process sudden changes in load on the vehicle's engine. If the clutch pedal position sensor is faulty, engine operation may be unstable (speeds fluctuate, jerking when releasing the gas), and error P0830 will appear.

Topic: Vesta clutch adjustment

I’ve driven the West for 1000 km and I can’t get used to the clutch, just when I’m moving off, well, the clutch grabs at the very end, so you still have to release it very slowly and for a long time in order to start normally and not stall the engine, and keep the speed at least 1500-1700. Is it so hard for everyone to start moving and is it possible to adjust the clutch? Before this I had a Priora, even if I let go of the clutch more frequently, I still pulled away confidently, but in the West the engine stalled.

Re: Vesta clutch adjustment

I got into the Vesta in the cabin and immediately took off and drove off. You probably don’t have enough experience; you need to feel when the engine is choke. And don’t forget that Vesta, unlike Priora, has a hydraulic clutch, not a cable.

Replacing the clutch pedal position sensor

On Lada Vesta and XRAY cars, removal and installation of the sensor is performed in the same way. It is located in the area of ​​the clutch pedal, next to the steering shaft:

Procedure:

1. Disconnect the block with wires (green) by pressing the latch.
2. Remove the sensor by turning it counterclockwise 90°.

Installation is carried out in the reverse order, with the brake pedal in its highest position.

How to adapt AMT

1. Turn on the ignition and connect to the car using the ELM327 adapter and DDT4ALL software.
2. Select in the upper left window XGA-XRAY - AT - BVR_On_CAN_x52_J53_v2.4
3. In the middle window BVR_On_CAN_x52_J53_v2.4
4. In the lower left After sales - Learning Procedures
5. Press the button with the image of a “face”
6. Carry out the learning procedure by clicking on the appropriate button.

1. Turn on the ignition, but do not start the engine. Carry out training of the
   clutch actuator end positions. Execution time is about 5-6 seconds. (you will hear the actuator moving).
2. After the operation, press the “STOP” button and turn off/on the ignition.
3. We wait 5-10 seconds and start the gearbox learning
   . We do not turn off the ignition. Execution time is about 1 minute.
4. After the operation, press the “STOP” button and turn off/on the ignition.
5. Start the engine and wait 15-20 seconds, then start learning the clutch touch point
   . Execution time 5-10 seconds.
6. After the operation, press the “STOP” button and turn off the ignition. Wait for the main relay to turn off (about 4 minutes)
7. We start the engine and check.

If after AMT adaptation the engine does not start

. It is possible that the last learning procedure was completed incorrectly and an error was stored in the memory of the electronic unit. It is necessary to perform diagnostics, reset errors, and perform adaptation again.

You can also perform AMT adaptation using OpenDiag Pro or Scanmatic software (see an example of such adaptation). Both programs are paid.

Have you ever had to adapt the AMT on a LADA yourself?

Let's remember that we previously told you how using ELM327 and DDT4ALL you can:

AvtoVAZ offered Lada Vesta buyers a cheap automated transmission, but forgot to talk about the prices for the further maintenance of the notorious AMT “robot”. But the world needs to know how much it actually costs to replace the actuators that are responsible for shifting gears.

If you were looking for the cheapest, but most understandable (and not Chinese) car with automatic gear shifting, then you should go straight to the official AvtoVAZ dealers for the new Lada Vesta. Not only does the Russian budget sedan itself cost less than popular models like Solaris, Rio and Polo, but also the surcharge for the two-pedal version of the Togliatti car is half that of its competitors - only 25 thousand rubles!

The secret of adequate cost is in the AMT robotic gearbox of AvtoVAZ’s own production, which was based on the modernized cable “mechanics” with the index 2180. The AMT 2182 unit was first tested on the Priora. German electric actuators manufactured by ZF are used here as the selection actuator. They are located in place of the conventional gear shift mechanism and on the outer end of the clutch fork. Essentially, this is the same 5-speed “mechanics”, and even the assembly of two transmissions is carried out on the same line. Hence the low cost of AMT. And the “robot” is only an insignificant 5 kg heavier than a manual transmission.

Checking the clutch pedal position sensor

Vesta and XRAY got the sensor from Renault (article 253250007R). To check it, you will need a multimeter (in ohmmeter mode).

Procedure:

1. Move the rod lock to the right position using a flat-head screwdriver.
2. Connect the multimeter probes to sensor terminals No. 3 and No. 4.
3. When the rod is in the free position, the circuit should be open (the resistance value approaches infinity).
4. When you press the rod, the circuit should close (the resistance value is close to zero).

We replace the faulty sensor with a new one.

Let us remind you that we previously talked about the brake pedal position sensor and the electronic gas pedal.

Connecting cruise control keys

To connect the cruise control keys, follow the procedure.

Connecting the buttons on the steering wheel begins with completing the wired cruise control system with the radio wiring. Connect the wiring to the multimedia device into the blue connector. To avoid mistakes, study the wiring diagrams.

If a new radio was installed during operation, you will need an adapter for the specific type of audio system.

- switching music files;

- Instant volume mute.

Cost of steering wheel with buttons

The price for the model with buttons depends on the store. Most Lada Vesta car owners purchase products with keys in virtual stores. The order is placed for article number 8450006832. The cost ranges from 5000 to 7000. If the vehicle owner needs an airbag, the price increases by another 1000-15000. For leather covering you will have to pay another 2000-2500 rubles.

To save money, you can use an overlay with keys on a standard steering wheel. This option is more difficult to connect and difficult to find, since it is not popular.

Lambda probe

Oxygen concentration sensor (part number 226A41771RF). Separates the gas flow in the exhaust manifold and informs the ECU about the gas concentration.

Installed on the outer wall of the exhaust manifold. Resource over 100,000 km. Cannot be repaired. Signs of inoperability:

• error indication on the dashboard.

Functions and purpose

The principle by which DPKV works is no different in complexity. The sensor needs to generate inductive signals. At the moment when the teeth of the wheel rotating the crankshaft pass the sensor core, alternating current pulses are generated. In other words, DPKV is an electromagnetic sensor. In the fuel system, it keeps the fuel injectors running in sync with the ignition

It is important for car enthusiasts to know that this is a very important part, without which the fuel system will not work properly and the engine will not start.

Today there are a large number of different DPKVs, since the global vehicle fleet is represented by vehicle models with a wide variety of characteristics. But regardless of the characteristics, all sensors have basic functions that do not differ from model to model: starting the engine or synchronizing the engine injectors. The DPKV performs its work together with the synchronization disk, which allows it to generate special impulses. If the sensor begins to perform its functions incorrectly, the fuel system cannot form the fuel-air mixture necessary for proper operation of the internal combustion engine. As a result, the car almost completely loses its performance. Let's try to take a closer look at the mechanism of operation. The sensor generates pulses that fully correspond to the moment of movement of the teeth near the ends of the part. The maximum value of the voltage change and the frequency of the pulse sequence will be directly proportional to the engine speed.

If it clicks when you release or squeeze the clutch of a Lada Vesta in the cabin, the reason may be in the limit switch, pedal support or hydraulic cylinder design. Knocks in the engine compartment are more serious - the dealer is less likely to refuse to find out their cause, since this may indicate a malfunction of important parts - springs, release bearings, working cylinder.

As a temporary solution to a serious knock, drivers use the accelerator. You need to get used to this: when the clutch is released, the driver applies more gas and the knocking disappears. Typically, such actions indicate defects in the release support guide.

Analogs

The manufacturers themselves recommend 826818 VALEO 2180 for Vesta. Owners note that when using the model, the pedal becomes noticeably softer and the car starts easily. The note applies to the original set; fakes are often found. The spare part costs four thousand eight hundred rubles.

The original part of the Lada Vesta is not suitable for the 21129 engine in terms of power; it is designed for lower speeds, for example, such as 2112. For 106 horsepower and above, TS-00001321 would not be a bad match. Price – five thousand six hundred rubles.

Signs of malfunction and their causes

So, having analyzed in detail the purpose of the DPKV, it becomes clear that the malfunction of this part disables the entire fuel system. To protect yourself from unexpected breakdowns, especially during long trips, diagnose the sensor and replace it if necessary.

But before that, be sure to familiarize yourself with what you should pay attention to. First of all, the driver needs to remember that the position sensor cannot operate with variable performance

In other words, it either performs its task well or does not perform it at all. So if the sensor becomes unusable, it becomes absolutely unrepairable.

There are not many reasons why the device could break. In most cases, breakdowns are accompanied by regular temperature overloads, which have a bad effect on the condition of the device. The body and filling are slowly but surely destroyed. The same applies to short-term temperature changes. Also, the sensor will not be able to work for a long time in high humidity conditions. A very common problem with crankshaft position sensors is worn wiring. Usually the wiring gets old and simply needs to be replaced with a new one. Only a specialist can accurately diagnose all “diseases”. Service station technicians use special diagnostic equipment, which can be used to check all elements of automotive wiring and electrical devices.

Also pay attention to the check engine sensor. If both it and the wiring are working properly, you will have to check the DPKV

If your car is not equipped with an engine condition sensor, you can do without it. Here's what you need to pay attention to:

• The car stalls because there is no idle speed;
• There is no reaction from the car to an attempt to start the ignition;
• The engine constantly stalls while the car is moving;
• Engine performance is significantly reduced;
• During increased load, detonation occurs in the engine.

If you notice several or one of these problems, then it makes sense not to wait, but to immediately go to the service station. There, specialists with the necessary equipment will quickly identify a specific malfunction and fix it. You will also be advised on how to avoid these troubles during further operation of the car. If you don’t have quick access to a service station or you don’t want to contact strangers, you can diagnose the crankshaft sensor yourself.

Jerks when starting off

If you notice that the movement is accompanied by twitching, this is a serious reason to seek help from specialists. The Lada Vesta can shake for various reasons (for example, ignition failures), but if it is the clutch mechanism that gives the effect, we are talking about scrap parts. Obsolescence will never be accompanied by jerks, but destruction, the breaking off of pieces of metal, manifests itself this way. The presence of freely moving debris can cause great damage to other Vesta nodes. It is recommended to carry out repairs immediately.
