What to Do When the Exhaust Controller is Abnormal?

[DelHazel]

Here are the reasons for abnormal car exhaust controller: 1. False fault: A fault code is reported, but the system works normally. This may be due to an operation exceeding the computer's control range, causing the computer to feedback a fault code. The code can be cleared first, and then check whether the fault code reappears. 2. Minor fault: The engine does not show obvious faults, but further inspection based on computer detection information reveals a real fault that does not affect normal driving or has minimal impact. It needs to be discovered and resolved promptly. 3. Major fault: Such faults can be felt through visual inspection and driving experience, and they severely affect the normal operation of the engine. Immediate repair is required.
