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.

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.

How to view VAZ 2114 faults through the dashboard

You can check for errors in your car yourself, without using OBD2, as follows.

1. Insert the key into the ignition.
2. Hold down the odometer key and, without releasing it, turn the key to the first position.
3. Release the key and look at the tidy. After this, the arrows will start running in a circle.
4. Next, press the key again and quickly release it. This will allow you to install the firmware version.
5. If you press the button on the dashboard again, fault codes will be displayed and they can be read.

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.
