How to solve the p0 122 fault code?

Solution to p0 122 fault code of Pacific Auto Network: First, check whether the plug of the accelerator pedal sensor is loose and the line is disconnected by cleaning the throttle, then choose to repair it by yourself or directly go to the 4S shop according to the severity of the problem, and finally clear the fault code after the fault is solved.

The P0 122 fault code indicates that the throttle/pedal position sensor/switch A circuit voltage is too low.

The fault causes of P0 122 fault code include open circuit of sensor signal circuit, short circuit of sensor signal circuit to ground, open circuit of sensor reference voltage circuit, failure of sensor itself or failure of electronic control module (PCM or ECM).

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. This fault code indicates that the signal voltage of electronic accelerator pedal position sensor A is lower than the calibrated minimum value (0. 17v).

After the vehicle fault is eliminated, it is generally necessary to clear the fault code. When clearing the code, it must be carried out in strict accordance with the fault code clearing method specified by the specific vehicle model, and it is absolutely impossible to remove the battery negative electrode casually to clear the automobile fault code.
