Was bedeutet der Fehlercode?
The ECM watches the mass air flow sensor signal and stores the code when the signal falls outside the normal range. In this case the fault is a short to ground, meaning the signal wire has made contact with the vehicle body. The result is that the engine works from a calculated air mass value and some monitoring functions are switched off.
Mögliche Ursachen
- Signal wire shorted to ground
- Loose or corroded connections
- Break in the signal wire
- Break in the voltage supply
- Contact resistance in the mass air flow sensor connector terminals
- Damaged mass air flow sensor
Was Sie tun können
- 1Read and note the code, clear it and road test to see whether it returns
- 2With a multimeter, check that the signal wire between the control module and the sensor has no break and is not touching ground
- 3Check that the connector at the mass air flow sensor is fully engaged and free from oxidation and play
- 4With a multimeter, check the supply wire from the system relay to the sensor for a break
- 5Look for chafed wiring that may have come into contact with the body
- 6If the fault remains, have a workshop check the mass air flow sensor
Symptome, die Sie bemerken können1
- The car lacks power and runs poorly
Was der Fehler beeinflussen kann3
- A calculated air mass value is used
- Rear lambda sensor control is switched off
- Misfire diagnosis is switched off
