Skoda Ming Rui fault code P0222

Throttle/pedal position sensor/switch B circuit voltage is low.

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 lower than the calibrated minimum value (0. 17V) within a set time period. The fault causes include sensor interface fault, short circuit to ground, sensor fault, electronic control module (PCM or ECM) fault, etc.
