Was bedeutet der Fehlercode?
The ECM monitors the mass air flow sensor signal and stores the code when it is too high or too low. Here the signal is too low. The fault concerns the comparison between the A-side and B-side sensors, and
Mögliche Ursachen
- Signal wire shorted to ground
Was Sie tun können
- 1Read and note the code, clear it and road test to see whether it returns
- 2Check that the connectors at the mass air flow sensors are fully engaged and free from oxidation
- 3With a multimeter, check that the signal wire is not shorted to ground
- 4If you have diagnostic equipment, compare the A-side and B-side sensor values in live data at idle
- 5If the fault remains, have a workshop check the mass air flow sensor
Symptome, die Sie bemerken können1
- The car has poor performance and lacks power
Was der Fehler beeinflussen kann2
- A calculated air mass value is used instead of the measured value
- Engine torque may be limited
