Hva betyr feilkoden?
The engine control module compares the measured air quantity with the expected one. If the air quantity is too low and the fuel mixture adjustment is at the same time outside its normal range, the code is set. The cause may be a leak, a blocked intake or poor contact at the air mass sensor.
Mulige årsaker
- Contact resistance or oxidation at the mass air flow connectors
- Air leakage in the intake system
- Blocked intake system
- Damaged mass air flow sensor
Hva du kan gjøre
- 1Check the mass air flow sensor connector for contact resistance and oxidation
- 2Check the hoses between the mass air flow sensor and the throttle unit for leaks and damage
- 3Check that the throttle housing is not contaminated, since dirt can block the air flow
- 4If the fault remains, have a workshop check the mass air flow sensor
Symptomer du kan merke2
- The malfunction indicator lamp comes on
- The engine performs worse
Hva feilen kan påvirke3
- Boost pressure is calculated instead of measured
- Rear oxygen sensor control is switched off
- Misfire detection is switched off
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
