Co oznacza ten kod błędu?

The engine control module has registered that the control signal reaching the fuel pressure valve is too weak. Engine speed can be limited because fuel pressure is not under proper control. The usual cause is a break or a short to ground in the wire, or poor contact at the connection.

Możliwe przyczyny

Loose connections, contact resistance or oxidation at the terminals
Break in the power supply to the valve
Break in the signal wire
Signal wire shorted to ground
Damaged fuel pressure control valve

Co możesz zrobić

1With the ignition off, check the connector to the fuel pressure control valve for play, contact resistance and oxidation
2Use a multimeter to check that the wire to the valve does not break when the harness is moved and has no contact with ground
3The fuel system is under very high pressure and can cause injury, so have a workshop carry out all work on the fuel lines and the valve
4If the fault returns after erasing codes and a test drive, have a workshop replace the fuel pressure control valve
