Hva betyr feilkoden?
The ECM tests whether the fuel injectors shut off properly when the engine stops. During shut-down the engine speed should fall as expected. If the ECM registers a faulty signal from the injector output stage, the code is set. A leak in the fuel system is one possible cause, but a defective pressure control valve, relief valve, injector or fuel pressure sensor can also set it.
Mulige årsaker
- Leakage in the fuel system
- Defective fuel pressure control valve
- Defective relief valve
- Defective injector
- Defective fuel pressure sensor
Hva du kan gjøre

- 5Have a workshop with diagnostic equipment check the fuel pressure and the pressure control if the fault remains
