Error P2135 - what it means, symptoms, causes, diagnosis, solution

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.

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 troubleshoot P0141?

This code can only be caused by problems in the DC heater circuit or the sensor itself.

Typically, heated sensors have four wires - two of which go to the heater circuit, and two for powering and grounding the sensor. In this case, we are dealing only with a circuit with a heater.

Typical DC heater circuit and connectors:

Source: alldata.com

Find the wiring diagram for your vehicle to make sure you are testing the correct wires.

Check heater circuit wiring

Disconnect the O2 sensor connector. Check the voltage and ground of the heater. You can do this using a digital multimeter.

After reviewing the wiring diagram for your vehicle, determine which pin on the connector is power and which is ground. Set the multimeter switch to "Constant Voltage".

Touch the black lead of the multimeter to the housing and the other to the power lead on the connector. You will see a reading close to the battery voltage. If not, you have a problem with the DC power supply. It will be necessary to examine the electrical circuit on the power side to determine the cause of the circuit failure.

To test the ground wire circuit, connect the red lead of the multimeter to the positive terminal of the battery and the black lead to the ground on the connector. You should see a voltage of about 12 volts. If this is not the case, you need to look for the cause of the circuit malfunction using the wiring diagram on the ground side.

Checking the heating element

If everything is fine with power and grounding, you need to check the sensor heating element for high resistance or an open circuit. This can be done using a digital multimeter.

Set the device to resistance measurement mode (Ohms). Then connect the multimeter leads to both contacts of the heater circuit on the sensor connector side.

Look up the specifications for your oxygen sensors to see if the resistance value is within normal limits. Otherwise, the heating element inside the sensor has high resistance and the sensor should be replaced.

If during the test you measure infinity, then there is a break in the heating element. In this case also the sensor must be replaced.

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.

Diagnosis of errors

When you begin to notice something unusual in the behavior of your car, or there are obvious problems in its operation, then it certainly makes sense to have it diagnosed. Naturally, the OBD-II diagnostic connector will show errors most efficiently and accurately, however, not everyone has sockets to control this connector and has to use the standard one.

In order to enter self-diagnosis mode, you must:

1. Turn off the ignition.
2. Click on the daily vehicle mileage button.
3. Then, continuing to hold it, turn the key in the lock.
4. Thanks to this, all available indicators will light up, and the dial indicators will go into self-test mode and show data from zero to maximum.
5. When this happens, use the button located on the steering column switch and use it to switch the data on the instrument panel.
6. To read the fault codes, we need the last one - the third screen. Unambiguous error codes will be displayed there.

Displaying the error code on the third screen of the bookmaker. The photo shows error 4 (faulty coolant temperature sensor).

Error codes (decoding)

These are the most common error codes that can appear if there is a malfunction on the Lada Kalina.

Code Explanation 2 Excess of voltage in the vehicle's on-board network. 3 Malfunction of the gasoline level sensor in the fuel tank

Possible circuit break. 4 When this code appears, the car owner needs to pay attention to the operation of the antifreeze temperature sensor. There is also a possibility of a circuit break. 5 There is a problem with the outside temperature sensor. 6 The control unit has detected engine overheating

It is recommended to deal with this problem before further operation of the car. 7 Emergency lubricant pressure in the internal combustion engine is reported. 8 If you see this code on the dashboard, then you need to check the functionality of the brake system. The on-board computer recorded an error or breakdown in its operation. 9 The on-board computer reports that the battery charge is too low. It is recommended to perform a more thorough check of the battery. E An error has been reported in the data packet stored in the EEPROM.

Checking the system using special equipment

If the system is checked through a diagnostic block using OBD-II, then the code combination will consist of four characters, preceded by a letter at the very beginning.

We connect the PC to the diagnostic connector of LADA Kalina

P - indicates a problem with the engine or transmission. C - displayed when an error occurs in the “running”. B - when such a letter designation appears, you should pay attention to the serviceability of the central locking system, airbags, and power windows.

The second digit means:

• 0 – common code for OBD-II;
• 1 – number of the car manufacturer;
• 2 – number of the car manufacturer;
• 3 – reserve code.

The third character refers directly to the type of failure:

• 1 – malfunction in the air supply system and fuel system.
• 2 – similar to code “1”.
• 3 – failures and malfunctions in the ignition system.
• 4 – auxiliary control.
• 5 – malfunctions during idle operation.
• 6 – malfunction of the ECU or its circuit.
• 7 and 8 – malfunction in the transmission.

Stages of diagnosis and repair

A few words about the electronic throttle. This system is incredibly sensitive and more vulnerable to damage than any other. Handle it with extreme care. One fall or rough handling and it cannot be restored.

Apart from the accelerator pedal sensor, the remaining components are located in the throttle body. Upon inspection, you will notice a flat plastic cover on the top of the throttle body. It contains mechanisms for actuating the throttle valve.

The motor has a small metal gear protruding through the housing under the cover. It drives a large "plastic" gear attached to the throttle body.

The pin that centers and supports the gearbox fits into the throttle body and into the “thin” plastic cover. If the cover becomes warped in any way, the transmission will be compromised, requiring a complete throttle body replacement.

• The first thing to do is go online and search for TSBs (Technical Service Bulletins) for your vehicle related to the code. These TSBs are the result of customer complaints or identified problems and the factory recommended repair procedure.
• Look on the Internet or in the service manual to see how you can retrain the control unit. For example, for Nissan you need to turn on the ignition and wait 3 seconds. Over the next 5 seconds, press and release the gas pedal 5 times. Wait 7 seconds, press and hold the pedal for 10 seconds. When the Check Engine light starts flashing, release the pedal. Wait 10 seconds, press the pedal again for 10 seconds and release. Turn off the ignition.
• If additional codes such as P2136 were present, fix them first as they are part of the system and could be the direct cause of the P2135 code.
• Pull the electrical connector out of the throttle body. Look for bent or missing terminals. Look for corrosion. Clean out the corrosion using a small flathead screwdriver. Apply a small amount of electrical grease to the connector and plug it back in.
• If the connector has bent or missing pins, you can get a new pigtail at most auto parts stores or your dealer.
• Inspect the throttle body top cover for cracks or deformation. If they do, call the dealer and ask if they only sell the top cap. If not, replace the throttle body.
• Use a multimeter to check the accelerator pedal sensor. For comparison, it will receive 5 volts and an alternating signal. Turn on the ignition key and slowly press the pedal. The voltage should rise smoothly from 0.5 to 5.0 volts. Replace it if there are voltage surges or no voltage on the signal wire.
• Find the wire assignments on your car's throttle body on a diagram or search. Check that the throttle body connector is receiving power to the throttle motor. Have an assistant turn on the key and lightly press the pedal. If there is no power, the ECU is faulty. If voltage comes, there is a malfunction in the throttle body.

Sensor malfunctions

The table shows a list of controller errors that in practice occur most often when diagnosing the Lada Kalina.

User Alexander Skripchenko spoke in detail about troubleshooting the Lada Kalina, as well as reading combinations.

Description and meaning of error P0422

This diagnostic trouble code (DTC) is a generic powertrain code, which means it applies to OBD-II equipped vehicles. While general, specific repair steps may vary depending on the make/model. A vehicle's catalytic converter (catalyst) helps improve tailpipe emissions by oxygenating the exhaust gases. It helps convert carbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx) into water vapor (H20), carbon dioxide (CO2), and nitrogen (N). The PCM (Powertrain Control Module) monitors catalyst efficiency through the catalyst post oxygen sensor. This sensor is mainly used for this purpose. It should shift much slower than the front oxygen sensors. If at any time the PCM detects that the catalytic converter O2 sensor is switching too quickly (without indicating any change between the input and output of the catalytic converter), then it interprets this as the catalyst not functioning properly. Bank 1 is the side of the engine with cylinder number 1.

Decoding: Lada Granta errors
