Hva betyr feilkoden?
The engine control module (ECM) controls the fuel pressure control valve, which keeps the correct pressure in the fuel system. The code is set when the control wire to the valve is faulty. The fault can stop the engine from starting or make it feel sluggish.
Mulige årsaker
- Control signal wire short-circuited to supply voltage
- Defective fuel pressure control valve
