Was bedeutet der Fehlercode?
The control module (ECM) controls the fuel pressure through the fuel pump and the fuel pressure regulator valve, and compares it with the sensor signal. The code is set when the pressure fails to change as required, or shows an offset, while the engine is switched off. The driver normally notices nothing, but the engine torque may be limited.
Mögliche Ursachen
- Contact resistance or oxidation in the connections to the fuel pressure regulator valve
- Clogged fuel filter
- Damaged fuel pressure regulator valve
- Damaged fuel pump
- Damaged fuel pressure sensor
Was Sie tun können
- 1Check that the fuses are intact
- 2Read and clear the code, then drive the car for a while to see whether it returns
- 3Check the connectors at the fuel pressure regulator valve for contact resistance and oxidation
- 4If you have a diagnostic tool: read the fuel pressure in live data and see whether it changes when the engine is loaded
- 5If the fault remains, a workshop should check the fuel pump, the pressure regulator valve and the fuel filter
Symptome, die Sie bemerken können1
- No noticeable symptoms for the driver
Was der Fehler beeinflussen kann1
- The engine torque may be limited
