What to Do When the Exhaust Controller is Abnormal?

[ChristopherLee]

Exhaust controller abnormalities can be caused by the following reasons and solutions: 1. False fault: A fault code is reported, but the system works normally. This may be due to an operation that exceeded the computer's control range, resulting in a fault code feedback. The code can be cleared first, and then check if the fault code reappears. 2. Minor fault: The engine does not show any obvious issues, but further inspection based on computer detection reveals a minor fault that does not significantly affect normal driving. It should be identified and resolved promptly. Examples include faults in the intake pressure sensor, etc.
