Hva betyr feilkoden?
The ECM weighs the mass air flow sensor temperature reading against coolant, outside, boost and oil temperature values. Here the air temperature is too low compared with those values, and the code is stored when the difference is too large.
Mulige årsaker
- Contact resistance in the connector terminal
- Mass air flow sensor with the air temperature sensor inside is damaged
Hva du kan gjøre
- 1Read and note the code, clear it and road test to see whether it returns
- 2Start the engine and, with diagnostic equipment, check that the air temperature in live data is reasonable; if it is not, the fault is present
- 3Check the mass air flow sensor connector for contact resistance and oxidation
- 4If the fault remains, have a workshop check the mass air flow sensor
Symptomer du kan merke1
- Engine warning lamp (check engine) lit or behaving abnormally
Hva feilen kan påvirke1
- The outside air temperature from the sensor in the rear-view mirror is used instead
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
