Hva betyr feilkoden?
The engine control module (ECM) has registered an internal fault, which shows that the calculated load signal is lower than the internal monitoring has worked out. The code is set while the engine runs above a certain speed.
Mulige årsaker
- Blocked exhaust system
- Blocked intake system
- Air leakage in the intake system
- Defective engine control module (ECM)
Hva du kan gjøre
- 1Check the intake and exhaust systems for blockages
- 2Check the intake system for air leakage, and the inside of the throttle housing for contamination. A dirty housing reduces airflow to the engine
- 3If the fault remains after these checks, a workshop should program or replace the engine control module if the fault is permanent
Symptomer du kan merke4
- Low maximum engine speed
- Cruise control does not work at all
- Uneven idle
- Malfunction indicator lamp lit
Hva feilen kan påvirke1
- Engine speed and torque are limited to a calculated reasonable value
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
