BYD f64g69 Engine Fault Code p2 122

Throttle/Accelerator Position Sensor/Switch D Circuit Low

Throttle/pedal position sensor/switch D circuit low.

Category: Fuel, Air or Emission Control

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. The fault causes include the accelerator pedal position (APP) sensor circuit open circuit or short circuit to ground, APP sensor itself fault, electronic control module (PCM or ECM) fault, etc.
