Hva betyr feilkoden?
The engine control module compares the fuel pressure in the fuel rail with the pressure it requests and logs a fault when they do not match. Causes can be poor contact at the pressure control valve or sensor, a blocked fuel filter, or a damaged pump, valve or sensor. The fault can make the car feel weak, and engine torque may be limited.
Mulige årsaker
- Loose connection, contact resistance or oxidation in the fuel pressure control valve connections
- Loose connection, contact resistance or oxidation in the fuel pressure sensor connections
- Blocked fuel filter
- Damaged fuel pressure sensor
- Damaged fuel pump
- Damaged fuel pressure control valve
Hva du kan gjøre
- 1Read the fault code, clear it and road test to see whether it returns
- 2Check that the connectors to the fuel pressure sensor and pressure control valve are fully engaged and free from oxidation
- 3The fuel system runs at very high pressure and can cause injury. Have a workshop check the pump, pressure control valve and injectors
- 4Check the fuel filter for clogging; a worn filter should be replaced by a workshop
- 5If you have a diagnostic tool, read fuel pressure in live data with the engine running. A pressure that does not follow the requested value points to the fault
- 6If the fault returns after clearing and a road test, have a workshop decide whether the fuel pressure sensor needs replacing
Symptomer du kan merke2
- Car drives poorly and lacks power
- Text message and warning symbol in the display
Hva feilen kan påvirke1
- Engine torque may be limited
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
