What is VW fault code P0222?

First of all, we need to understand the meaning of Volkswagen fault code P0222, which means that the accelerator/pedal position sensor/switch B circuit is low.

1, failure reason:

(1) Basic fault causes include sensor interface fault, short circuit to ground, sensor fault, electronic control module (PCM or ECM) fault, etc. Specific problems can only be determined after detailed inspection, and the scope of investigation can be narrowed by referring to the fault scope.

Extended data:

1, meaning and analysis of fault P0222:

(1) This OBD fault code is applicable to all automobile manufacturers.

(2) English meaning: The circuit of accelerator/pedal position sensor/switch B is low.

(3) English meaning: accelerator/pedal sensor/switch circuit

(4) Category: fuel or air.

(5) Detailed meaning: 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 circuit voltage of accelerator pedal position sensor B is continuously lower than the calibrated minimum value (0. 17V) within the set time.

(5) Cause: Failure causes include sensor interface failure, short circuit to ground, sensor failure, electronic control module (PCM or ECM) failure, etc.
