Hva betyr feilkoden?
Although the code is named signal missing, it applies when the fuel pressure sensor reading is uneven or unreasonable. The engine control module monitors the signal and logs a fault when it falls outside the permitted range. The cause is either poor contact in the connectors or a damaged sensor.
Mulige årsaker
- Loose connection, contact resistance or oxidation in the connectors
- Damaged fuel pressure sensor
Hva du kan gjøre
- 1Read the fault code, clear it and road test to see whether it returns
- 2Check that the connector at the fuel pressure sensor is fully engaged and free from oxidation
- 3The fuel system runs at very high pressure and can cause injury. Have a workshop make pressure checks
- 4Follow the wiring from the sensor and look for looseness, chafing and loose clips
- 5If you have a diagnostic tool, check in live data whether fuel pressure reads steadily with the engine running. An uneven value points to the sensor or connector
- 6If the fault returns after a road test, have a workshop decide whether the sensor should be replaced
Symptomer du kan merke2
- Car drives poorly and lacks power
- Text message and warning symbol in the display
Hva feilen kan påvirke1
- Engine torque may be limited
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
