Hva betyr feilkoden?

The ECM monitors the B-side mass air flow sensor signal. The code is stored when the signal is too high, too low or otherwise incorrect. Here the signal lies outside the expected range, and the result can be that engine torque is limited.

Mulige årsaker

Poor contact, high resistance or corrosion in the connections
Break in the signal wire
Signal wire shorted to supply voltage
Signal wire shorted to ground

Hva du kan gjøre

1Read and note the code, clear it and road test to see whether it returns
2Check that the connectors at the B-side mass air flow sensor are fully engaged and free from oxidation and play
3With a multimeter, check that the signal wire has no break and is not shorted to ground or supply voltage
4If you have diagnostic equipment, read the B-side sensor value in live data at idle and check that it follows engine load
5If the fault remains, have a workshop check the B-side mass air flow sensor

Symptomer du kan merke3

Engine warning lamp (check engine) lit or behaving abnormally
The car lacks power and runs poorly
Text message in the display

Hva feilen kan påvirke2

Engine torque may be limited
A calculated air mass value is used instead of the measured value
