Hva betyr feilkoden?
The code indicates a low signal from outside temperature sensor A, and the condition is that the value deviates too much from the other sensors. After the engine has been off for a long time, the engine control module compares the outside temperature with the air temperature in the mass air flow sensor, the boost pressure sensor temperature, the coolant, the oil and the intake manifold temperature sensor.
Mulige årsaker
- Contact resistance in the sensor connector
- Outside temperature sensor A is damaged
Hva du kan gjøre
- 1If you have a diagnostic tool, read the outside temperature in live data with the ignition on and see whether the value is plausible
- 2Read the fault code with a diagnostic tool and note whether it is active or only stored
- 3With the ignition off, check the sensor connector and terminals for contact resistance and oxidation
- 4Correct what you find in the connector and make sure it is firmly seated
- 5If the connector is clean and the fault remains, have a workshop check the sensor
Symptomer du kan merke1
- No noticeable symptoms for the driver
Hva feilen kan påvirke1
- The outside temperature is calculated instead of measured
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
