Was bedeutet der Fehlercode?

The engine control module (ECM) takes its rail pressure reading from the sensor and checks that it stays within limits. The fault code is set when the fuel pressure is too high. It can be caused by a damaged fuel pressure sensor or a damaged fuel pressure control valve.

Mögliche Ursachen

Damaged fuel pressure sensor
Damaged fuel pressure control valve

Was Sie tun können

1Check the connector at the fuel pressure sensor for contact resistance and oxidation
2Look for damage on the sensor cable and check that it is not pinched
3If you have a diagnostic tool: read the fuel pressure in live data with the engine running and compare it with the pressure the control module requests
4Have a workshop check the fuel pressure sensor with a gauge, and the fuel pressure control valve
5After the repair, read off the fault code and check that it does not come back

Symptome, die Sie bemerken können2

The car lacks power while driving

Was der Fehler beeinflussen kann1
