Was bedeutet der Fehlercode?

The rear electronic module (REM) keeps track of the signal from the gas level sensor. If the signal is too high, the code is stored. The cause can be an open circuit in the sensor, a sensor shorted to battery voltage, or a signal wire shorted to supply voltage. The fuel level is then set to zero.

Mögliche Ursachen

Open circuit in the gas fuel level sensor
The gas fuel level sensor is shorted to battery voltage
The signal wire is shorted to supply voltage

Was Sie tun können

1Read the fault code, clear it and test drive the car to see whether it returns
2Check that the connector to the gas fuel level sensor is secure and free from oxidation and damage
3Use a multimeter to check that the signal wire has no voltage when the ignition is off
4If the fault remains, have a workshop replace the gas fuel level sensor

Symptome, die Sie bemerken können4

The trip computer shows the tank empty too early
The fuel gauge does not work
The fuel gauge reads zero although there is fuel in the tank
The gas level gauge does not work

Was der Fehler beeinflussen kann1
