Hva betyr feilkoden?
This variant applies to the C30, C30 Electric, C70, S40 and V50. The CEM registers that the fuel level sensor circuit or the DC/AC converter is shorted to ground. The fuel gauge then shows too low a level, and the fuel level is set to zero.
Mulige årsaker
- A damaged fuel level sensor
- An internal fault in the DC/AC converter
Hva du kan gjøre
- 1With the ignition on, check whether the fuel gauge shows a level that matches the fuel in the tank
- 2Check that the connectors at the CEM and at the fuel pump are seated and not corroded
- 3Use a multimeter to check that the wire to the sensor is not shorted to ground
- 4If the wires are intact and the fault remains, have a workshop replace the sensor or the DC/AC converter, since this needs access to the tank
- 5After the work, clear the code and check that the level is shown correctly
Symptomer du kan merke2
- The trip computer shows an empty tank too early
- The fuel gauge shows the wrong fuel level
Hva feilen kan påvirke1
- The fuel level is set to zero
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
