Was bedeutet der Fehlercode?

The ECM continuously checks that the mass air flow sensor signal is plausible. The code is stored when the sensor signal is implausible, and the fault is described as an interrupted circuit. The fault is listed as intermittent, so it may come and go and may not be present when the car is checked.

Mögliche Ursachen

Contact resistance or oxidation in the connector terminals
Break in the voltage supply
Break in the signal wire
Signal wire shorted to ground
Signal wire shorted to supply voltage
Damaged mass air flow sensor

Was Sie tun können

1Read and note the code, clear it and road test to see whether it returns
2Make sure the relevant fuses are intact
3Check that the connectors at the mass air flow sensor are fully engaged and free from oxidation
4With a multimeter, check that the signal wire has continuity and is not shorted to ground or supply voltage
5If you have diagnostic equipment, read the fault status after the road test; a fault that is still active is present now
6If the fault remains, have a workshop check the mass air flow sensor

Symptome, die Sie bemerken können1

Engine warning lamp (check engine) lit or behaving abnormally

Was der Fehler beeinflussen kann1

A calculated air mass value is used
