What Causes Abnormal Exhaust Controller?

[AbigailRose]

Abnormal exhaust controller causes are as follows: Code malfunction: Fault code is reported but operation is normal, possibly due to an operation exceeding the computer's control range. The fault code fed back by the computer can be cleared first. Intake pressure sensor malfunction: According to computer detection information and further inspection, certain faults are found that do not affect normal driving or have minimal impact, indicating an intake pressure sensor malfunction that requires timely detection and resolution. Oxygen sensor malfunction: When driving experience shows severe impact on normal engine operation, it's an oxygen sensor issue requiring immediate repair.
