Was bedeutet der Fehlercode?

The control module (ECM) reads the fuel pressure in the low-pressure system from a fuel pressure sensor and checks the sensor's DC voltage. The code is set when the signal level falls below the lowest permitted value, and the wrong value must be present in two or more drive cycles in a row. The fault is detected while the ignition is on.

Mögliche Ursachen

Open circuit in the signal or earth wire to the fuel pressure sensor
Contact resistance or oxidation in the connections
Signal wire shorted to earth
Damaged fuel pressure sensor
Loose connection at the sensor

Was Sie tun können

1Read and clear the code, then run the engine to see whether it returns
2Check the connector at the fuel pressure sensor for looseness, oxidation and damage
3Use a multimeter to check that the signal and earth wires to the sensor have no break, and that the signal wire is not shorted to earth
4If you have a diagnostic tool: read the fuel pressure in live data and see whether the value changes when the engine is loaded
5If the fault remains after these checks, a workshop should check the sensor and its signal

Symptome, die Sie bemerken können1

The Check engine lamp lights up or behaves abnormally

Was der Fehler beeinflussen kann2

A fixed fuel pressure value is used
The fuel pump is controlled with a constant signal
