Was bedeutet der Fehlercode?

The engine control module (ECM) monitors the high pressure side of the fuel system. The code is set when the pressure reported by the sensor there is unreasonably low, which points to a fault on the high pressure side. The cause may be a leak, poor connections, a damaged sensor or a damaged fuel pump.

Mögliche Ursachen

Leak in the fuel system
Contact resistance or oxidation in the connections
Signal wire shorted to supply voltage
Open circuit in the signal wire or the signal ground wire
Damaged fuel pressure sensor
Damaged fuel pump

Was Sie tun können

1Look for leaks on the high pressure side of the fuel system, for example at connections and pipes, and fix any faults
2Check other fault codes in the control module that could affect the fuel system before replacing any part
3Note the conditions when the symptoms occur, for example at idle or when the car hesitates, and tell the workshop
4If you find no fault: have a workshop replace the high pressure fuel pressure sensor
5If the fault returns after repair: have a workshop check the high pressure fuel pump

Symptome, die Sie bemerken können2

Uneven idle
Hesitation, surging or jerky running while driving, either occasionally or all the time
