Was bedeutet der Fehlercode?
The engine control module has intermittently received a signal from the fuel temperature sensor that is too low, or has found a fault on its wiring. Engine management can then use a fixed value instead of the real fuel temperature. The fault is intermittent and may not be present right now.
Mögliche Ursachen
- Signal wire short-circuited to ground
- Signal wire short-circuited to supply voltage
- Open circuit in the signal wire
- Fault in the injection pump
Was Sie tun können
- 1Read and note the code, clear it and road test to see whether it returns
- 2Check the fuel temperature sensor connector for play, contact resistance and oxidation
- 3Use a multimeter to check that the signal wire is not broken and has no contact with ground or voltage
- 4If the fault remains, have a workshop with diagnostic equipment check the sensor and the injection pump
Symptome, die Sie bemerken können1
- The malfunction indicator lamp comes on
Was der Fehler beeinflussen kann1
- The engine control module uses a fixed value for the fuel temperature
