What does Chery Tiggo fault code P2 106 mean?

After the electronic throttle fault code appears, it cannot be ruled out. Do not blindly replace the electronic throttle body. Even if the electronic throttle body is replaced, if the fault is not eliminated, the fault light will light up again. It is necessary to carefully check the relevant wiring harness and clean the throttle body according to the prompt of the fault code before solving it. The probability of real equipment damage is very low.

The electronic throttle body shall be cleaned at least once every 20,000 kilometers according to the requirements of the mechanical valve body. Thereby reducing the failure rate.

Throttle body parts (ECM black connector)

Pedal electronic accelerator pedal parts (ECM brown connector)

2.ETC fault code can be divided into two parts; A part of the throttle body; Pedal electronic throttle part.

2. 1 throttle body parts P0 122, P0 123, P0222, P0223.

Such fault codes are ETC throttle position sensor signal line TPS 1, TPS2 low voltage or ground, high voltage or open circuit. This kind of fault is mostly caused by grounding, grounding or open circuit at a certain point in the routing bundle. For example, an open circuit of TPS2 will report P0223(ETC throttle position sensor 2# line voltage is high or open) fault, so it is necessary to distinguish between grounding and open circuit.

2. 1. 1 correlation of throttle position sensor P2 135

Whether the difference between the two throttle position sensors exceeds the calibration limit. At present, the calibration value is 4.5%, that is, when the difference between two TPS signals is greater than 4.5% and the time indicated by the diagnostic counter continues, the fault is reported. The sum of the signal voltage values of the two position sensors should be 5V.

If the signal voltage value of the throttle position sensor is not 5V due to poor contact or interference from two other sensor signal lines, this fault code will also be reported. It is also possible that the throttle position sensor itself is faulty.

Pay attention when troubleshooting this part of the fault code; First of all, you should carefully check the reliability of the connector.

2.2 pedal electronic throttle parts P2 122, P2 123, P2 127, P2 128.

Such fault codes are pedal throttle position sensor signal lines PDS 1 and PDS2 with low voltage or grounding, high voltage or open circuit. This kind of fault is mostly caused by grounding, grounding or open circuit at a certain point in the routing bundle. For example, PDS2 disconnection will report P2 123(ETC electronic accelerator pedal position sensor 1# line high voltage) fault, so it is necessary to distinguish between grounding and disconnection.

2.2. 1 pedal electronic accelerator pedal position sensor correlation P2 138

Whether the difference between the two electronic accelerator pedal position sensors exceeds the calibration limit. The current calibration value is 4.5%, that is, when the difference between the two PDS signals is greater than 4.5%, and the fault is reported after the time displayed by the diagnostic counter continues. The sum of the signal voltage values of the two pedal electronic accelerator pedal position sensors shall be 5V.

If the signal voltage of the throttle position sensor is not 5V due to poor contact or interference of the signal wires of the other two pedal electronic accelerator pedal sensors, this fault code will also be reported. It may also be caused by the failure of the electronic pedal itself or the unexpected large resistance of the wiring harness.

Pay attention when troubleshooting this part of the fault code; There are two intermediate transition connectors between the harness of pedal electronic throttle position sensor and the computer, which often leads to poor contact and is often ignored.

3. System function diagnosis fault code:

3. 1P2 106:

This fault code is a running mode of the engine, and the fault code itself is the result of other faults and plays a role in safety protection. The report of the fault is determined by ETCMODE, which is determined by a series of fault diagnosis states (including the diagnosis of non-ETC or APS itself), and usually exists with TPS or APS fault codes.

3.2P2 1 10

The fault code is similar to P2 106, which is a working mode of the engine. This fault code itself is the result of other faults and plays a role in safety protection. The report of the fault is determined by ETCMODE, and the determination of ETC mode is determined by a series of fault diagnosis states (including the diagnosis of non-ETC or APS itself). However, the controlled state of the engine represented by this mode is more serious than P2 106, which means that the engine control system has more serious problems than P2 106. After entering this operation mode, the ECM will control the torque output by disconnecting the cylinder and adjusting the ignition angle. At this time, the fuel exits the closed-loop control, which will have a great impact on emissions. The typical fault phenomenon is weak acceleration.

When troubleshooting such fault codes; First of all, the throttle body should be cleaned to reduce the problem that the computer control exceeds the standard requirements and reports the fault code because the throttle body is too dirty.

4. Actuator throttle motor drive part P2 10 1,

The fault code is an ETC actuator line fault. Usually, this kind of fault is caused by virtual connection and open circuit of harness or connector.
