Hva betyr feilkoden?
The module has detected an internal fault in its own analogue-to-digital conversion, the stage that turns sensor signals into values it can calculate with. Because the fault lies inside the module itself rather than in a sensor, the module is the likely cause. While the fault is present the engine may limit speed and torque to a calculated normal value.
Mulige årsaker
- Damaged engine control module (ECM)
Hva du kan gjøre
- 1Read the code, clear it and road test the car to see whether it returns
- 2Check that the battery is in good condition and that the engine control module connectors are fully seated and free from oxidation
- 3If the fault returns after the road test, the module is probably damaged and should be replaced; leave this to a workshop
Symptomer du kan merke4
- Maximum engine speed is lower than normal
- Cruise control does not work at all
- Uneven idle
- Malfunction indicator lamp (MIL) is on
Hva feilen kan påvirke1
- Engine speed and torque are capped at a level the module calculates as normal
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
