How to solve the fault code P0222?

P0222 fault code meets the objective requirements of all automobile manufacturers, indicating that the circuit of accelerator/pedal position sensor/switch B is low.

Background: In the electronic throttle control system, the function of the accelerator pedal position sensor is to transmit the position of the accelerator pedal to the throttle control module in the form of electrical signals, which can be used as a reference for the throttle actuator to adjust the throttle opening. This fault code indicates that the circuit voltage of accelerator pedal position sensor B has been below the calibrated minimum value for some time. The fault causes include sensor interface fault, short circuit to ground, sensor itself fault, electronic adjustment module fault, etc.

When the car has eliminated the fault problem, it is often necessary to clear the fault code. When clearing the fault code, the fault code clearing method specified by the specific vehicle model should be strictly followed. In order to clear the fault code, it is necessary to directly remove the negative grounding wire of the battery. Otherwise, there may be two abnormal situations mentioned below: First, some models of control center computers lose their normal records. We know that the control computer of some models has automatic memory function, and the engine operation data stored in RAM will be automatically cleared after the negative grounding wire of the battery is easily removed. This is also why some people find that after maintenance and cleaning, the performance symptoms basically do not drip for a long time, and there may be processed fault codes after long-term driving; Second, it will also cause the loss of some functions. For example, the audio locking function is one of the common situations. In this case, besides, the stereo needs to be repaired. @20 19
