The total air flow reported by BMW x 1n46 engine is not credible. What is the reason?
If this does not affect your normal driving, you can ignore it. It is best to go to the 4S store to monitor it. There are special monitoring instruments. The unreliable signal of the air flow sensor means that the engine control unit thinks that the data fed back by the air flow sensor is unreliable, and further understanding is that the data output by the air flow sensor is deviated from the theoretical data stored by the control unit. There may be several reasons for this failure: ① The signal error caused by the failure of the air flow sensor itself, or the air flow sensor is not clean. ② The wiring harness of the air flow sensor is faulty; ③ The engine control unit itself is faulty; ④ The air intake system itself is not sealed, resulting in leakage.
