Hva betyr feilkoden?
The ECM reads fuel pressure in the rail. If the pressure is too high and the fault is active, the module reduces the fuel supply. Causes can be air in the fuel, a blocked return line, or a damaged sensor or valve.
Mulige årsaker
- The car has run with an empty tank
- Air in the fuel
- Blockage in the fuel return line
- Damaged fuel pressure sensor
- Damaged fuel pressure control valve
Hva du kan gjøre
- 1Read and note the code, clear it and road test to see whether it returns
- 2Look for fuel leaks in the fuel lines between the tank and the engine, since air in the fuel can come from there
- 3Check the plugs of the pressure control valve and the pressure sensor for contact resistance and oxidation
- 4If you have a diagnostic tool: activate the fuel pressure control valve and check that the fuel pressure in live data rises
- 5Have a workshop check the return line and the pressure sensor, and once the fault is fixed also replace the pressure safety valve, since high pressure may have damaged it
Symptomer du kan merke4
- Noise from the engine, especially at idle
- The engine jerks
- The engine feels sluggish
- Engine speed is limited
Hva feilen kan påvirke1
- Fuel supply is reduced for as long as the fault is active
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
