Hva betyr feilkoden?
The ECM tests the fuel temperature sensor's signal. The fault code is set when the value differs too much from the coolant and intake temperatures following a long period with the engine off.
Mulige årsaker
- Contact resistance in the connectors
- Damaged fuel temperature sensor
Hva du kan gjøre
- 1Look at the connector at the fuel temperature sensor and check that it is secure and free of oxidation
- 2Leave the engine switched off for a long period, then start it and read the fuel, coolant and intake temperatures in live data. Without a diagnostic tool, a workshop can do this
- 3Clear the code and road test to see whether it returns
- 4The sensor is built into the fuel pressure sensor. Have a workshop check or replace it if the fault remains
Symptomer du kan merke1
- No noticeable symptoms for the driver
Hva feilen kan påvirke1
- The module calculates the fuel temperature instead
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
