Was bedeutet der Fehlercode?
The ECM compares the pressure it requests with the actual pressure in the fuel rail. If the actual pressure varies or pulses too much, the code is set. The fault is therefore about an irregular pressure rather than a pressure that is too high or too low.
Mögliche Ursachen
- The relief valve in the pump is stuck
- Leakage in the fuel lines up to the fuel rail
- The fuel pressure sensor is defective
- The fuel pump is defective
Was Sie tun können
- 1Fix any fault codes for the fuel pump control module first, since this code may then be a follow-on fault
- 2Make sure there is fuel in the tank: a nearly empty tank can give a false pressure reading
- 3Check the fuel lines and the fuel filter for blockage and leaks
- 4Check the connectors at the engine control module, the fuel pump and the fuel pressure sensor for contact resistance and oxidation
- 5With diagnostic equipment, read the fuel pressure sensor's value at idle and see whether it varies or pulses more than normal
- 6Have a workshop measure the fuel pressure and check the fuel pump, then try a new fuel pressure sensor if the fault remains
Symptome, die Sie bemerken können4
- Malfunction indicator lamp (MIL) on
- The engine misfires
- The engine stalls
- The engine hesitates or surges unevenly during acceleration and deceleration
Was der Fehler beeinflussen kann2
- The fuel pump shuts off if the fuel pressure deviates a lot
- The fuel pump is controlled with a calculated value
