The manufacturer of a budget car has provided the opportunity to repair the car yourself. VAZ 2114 error codes can be read by yourself or using external equipment. Typical symbols are displayed on the dashboard and indicate the presence of a specific problem in the on-board circuits of the machine. In the minimum configurations, the indication is made as a special light on the tidy. More advanced versions, which have a BC on board with a remote display, display the indication on a special screen. This makes it easier to read the data and understand where exactly the fault is located. All fault codes are displayed in two-digit codes, which greatly complicates the repair procedure. On-board systems can only indicate the area where the problem is located. For more specific diagnostics, you will need a special scanner.
Error codes for VAZ 2114 with an injection engine of 8 and 16 valves: decoding
The eight-valve Lada engine and the more advanced “shesnar” do not differ radically in design. The list of faults and their causes are usually identical, which makes it easier to diagnose cars in different trim levels.
Below are the most common problems and malfunctions encountered when diagnosing a car.

Already available in the description above.
Misfire: Causes
The causes of the problems are problems with the electronic ignition system. It is necessary to check the lines from the coils to the spark plugs.
ECU error
If problems arise with the controller, it is recommended to seek professional help. Do-it-yourself repairs can cause even more complex problems.
On-board network malfunctions
The problems are due to the fact that the voltage in the lines is too low or too high. There may be several errors, the numbers are scattered across the fault table.
The solution to the problem depends on the specific malfunction.
External RAM error
Controller malfunctions require qualified repair and maintenance. If there are problems with the device, you should contact an electronics technician.
Lambda probe error
It all depends on the wiring. The system malfunctions due to damaged wiring or oxidation of contacts. The module may also provide incorrect data due to catalyst wear.
TPS malfunctions
The throttle valve generates errors associated with incorrect operation of the drive. The position of the damper is controlled by a servomotor, weak enough to rotate the part in the coked housing.
If the module malfunctions, it is enough to clean the inductor and check the contact groups of the sensors.
Error DK1
Issues codes related to its own functionality or improper operation of the system, formation of the fuel mixture. If the sensor is working properly and transmits signals correctly, problems should be looked for in the throttle valve settings and ignition system.
Catalyst error
Occur when the catalyst efficiency is insufficient. Most car enthusiasts cut out the worn-out module and reflash the ECU to EURO-2/3 class. You can also replace the part, but its price deters most drivers.
Additional solution methods
Also, to solve the problem, you can adapt the throttle valve (start the engine at least 30 seconds after turning on the ignition, while its temperature should not be lower than +7°C).
The error can be diagnosed using a voltmeter. So, the cause of its occurrence can be one of two situations:
- the difference between the output voltage of VTA1 and VTA2 is less than 0.02 V for more than 0.5 s;
- The output voltage of VTA1 is less than 0.2V and VTA2 is less than 1.75V for more than 0.4s.
One of the possible causes of error p2135 is a malfunction of the throttle sensor (wear of the resistive layer, “contact bounce”, short circuit between circuits VTA1 and VTA2). In this case, it is necessary to replace the TPS or EMDU.
Replacing TPS on a VAZ 2115 car
Common cause of error P2135 on VAZ cars
If you own a VAZ car with an ignition system harness manufactured at the Tolyatti plant, it is recommended to replace it with a better one. If your car is still under warranty, entrust it to the specialists. The problem lies in the low quality of the insulation and wires included in its composition. An excellent alternative would be the ignition system harness produced by PES/SKK CJSC.
Occasionally, the car's ECU malfunctions and a one-time error signal may appear, which subsequently does not repeat. In this case, as well as in the case of replacing the TPS, it is necessary to reset the ECU and then initialize it. However, when replacing the sensor, you can get by by simply removing the negative terminal from the battery for 10 minutes.
I would like to note that the error in the remote control position sensor is typical not only for our domestic cars, such as the VAZ 2114. It often worries the owners of the Opel Astra, Chevrolet Aveo, and Ford Focus.
How to view VAZ 2114 faults through the dashboard
You can check for errors in your car yourself, without using OBD2, as follows.
- Insert the key into the ignition.
- Hold down the odometer key and, without releasing it, turn the key to the first position.
- Release the key and look at the tidy. After this, the arrows will start running in a circle.
- Next, press the key again and quickly release it. This will allow you to install the firmware version.
- If you press the button on the dashboard again, fault codes will be displayed and they can be read.
Causes
- Often the problem is in the connectors or wiring on the throttle body.
- Wiring shorted to ground.
- Damage to the throttle body cover, preventing the gears from rotating properly.
- Faulty electronic throttle body.
- The accelerator pedal sensor or its wiring is faulty.
- Control unit malfunction (rare).
- The throttle sensors have been out of tune for a few seconds and the ECU needs several cycles to relearn the throttle or the controller needs to be reprogrammed at the dealer.
