Hva betyr feilkoden?
The control module (ECM) compares the four pressure sensors in the injectors with each other against a highest permitted value. The code is set when any signal goes above the highest value. The fault is intermittent, meaning sporadic, and it may only be present some of the time.
Mulige årsaker
- Poor contact in the connections to the injectors
- The sensor in one of the injectors is faulty
Hva du kan gjøre
- 1Check the injector connectors for looseness and oxidation
- 2Clear the code and start the engine to see whether it returns
- 3If you have a diagnostic tool: read the pressure from each injector in live data and see whether any one is clearly high compared with the others
- 4If the fault remains, a workshop with diagnostic equipment should check the pressure sensor in the injector that differs
Symptomer du kan merke2
- Uneven idle
- The engine may stall at idle or while driving
Hva feilen kan påvirke1
- The value from pressure sensor 4 is used instead
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
