What does this fault code mean?
The rear electronic module (REM) watches the output of the gas level sensor. When that output is too low, the code is set, and the cause may be a signal wire shorted to ground or a faulty sensor. The fuel level is then set to zero and the gas level gauge does not work.
Possible causes
- The signal wire is shorted to ground
- The gas level sensor is defective
What you can do
- 1Clear the fault code and test drive the car to see whether it comes back
- 2Check the connector to the gas level sensor for damage and loose contacts
- 3Use a multimeter to check that the signal wire is not shorted to ground and has no break
- 4If the fault remains, have a workshop replace the gas level sensor
