P0322 What is the reason for not finding the fault code?
Background knowledge: Fault causes include engine speed sensor fault, sensor wheel fault or mismatch, electronic control module (PCM or ECM) fault, etc.
Clear the fault code every time after troubleshooting the car. When clearing the code, it must be carried out according to the fault code clearing method specified by the specified vehicle model, and it should be noted that the negative grounding wire of the battery cannot be removed casually to clear the fault code. Otherwise, it is likely to cause the following two problems: First, the control center computer of some models will lose normal records. As we all know, some models of control computers have automatic memory function. After the battery negative grounding wire is removed, the useful data of engine operation stored in the random access memory will be erased, resulting in poor performance of your car for a long time after maintenance, and the processed fault code may appear again after driving for a short time; Secondly, sometimes some useful functions will not work, such as audio lock is one of the more common examples. In this case, if you want to repair the stereo, it is equivalent to picking up sesame seeds and losing watermelon.
