Hva betyr feilkoden?
The engine control module compares the intake air temperature sensor with the engine and outside temperature sensors after the car has been switched off for a long time. If the air temperature deviates too much from the other sensors' values, the code is set. The code is checked with the ignition on, once the engine has cooled down properly.
Mulige årsaker
- Faulty signal from the intake air temperature sensor, which sits in the mass air flow sensor
- Contact resistance in the connector
- Damaged intake air temperature sensor inside the mass air flow sensor
Hva du kan gjøre
- 1With your own diagnostic tool, compare the air temperature in live data with the engine temperature after a night without driving; the values should be close
- 2Check that the mass air flow sensor connector is secure and free from oxidation
- 3Clear the code and road test to see whether it returns
- 4If the temperature is now correct, the fault was probably caused by poor contact in the connector
- 5If the fault remains, have a workshop replace the mass air flow sensor, since the air temperature sensor is part of it and cannot be replaced separately
