How to solve the failure code of Liwei Tiida p2 138?

Replace the accelerator pedal of the car.

P2 138 fault code is applicable to all automobile manufacturers, indicating the D/E voltage correlation of throttle/accelerator pedal position sensor/switch.

In the Electronic Throttle Control (ETC) system, the function of the accelerator pedal position (APP) sensor is to transmit the position of the accelerator pedal to the throttle control module in the form of an electrical signal, which serves as a reference for the throttle actuator to control the throttle opening.

If this kind of fault still exists after replacing the accelerator pedal, first clear the fault code with a scan tool, and then test run to see if the fault code reappears. If it appears again, the circuit between the accelerator pedal position sensor and the engine control module is faulty, and the circuit should be checked.
