There is still a fault code after cleaning the throttle.
After cleaning the electronic throttle, the Great Wall M4 fault light is on and the idle speed is unstable. The fault code is P0 122. Analysis:
P0 122: The signal circuit voltage of electronic throttle sensor is low.
Causes of failure: open circuit of sensor signal circuit, short circuit of sensor signal circuit to ground, open circuit of sensor reference voltage circuit, failure of sensor itself, or failure of electronic module (PCM or ECM), etc. If all the above are normal, match the throttle with the automobile computer tester.
