Automobile fault code Haima p022 1
P022 1 fault code, indicating throttle/pedal position sensor/switch B circuit range/performance. 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 the throttle pedal position sensor B is out of the normal range when the throttle is closed or fully opened. Causes of failure include throttle body failure, stuck throttle connecting rod, sensor circuit, interface or self-failure.
When your car breaks down, you need to clear the fault code. When clearing the fault code, it should be carried out in strict accordance with the fault code clearing method specified by the specific vehicle model, and it is absolutely impossible to simply remove the negative grounding wire of the battery to clear the fault code.
