Was bedeutet der Fehlercode?
The rear electronic module (REM) monitors the signal from the gas temperature sensor. If the signal becomes too high, for example because the signal wire is shorted to supply voltage, the code is stored. The fault can affect the fuel level reading, so the gauge may read zero while fuel is still in the tank.
Mögliche Ursachen
- Short circuit to supply voltage in the signal wire
- Break in the signal wire
- Defective gas temperature sensor
Was Sie tun können
- 1Note the fault code, clear it and test drive the car to see whether it comes back
- 2Check the connector to the gas temperature sensor for oxidation and damage
- 3Use a multimeter to check that the signal wire from the gas temperature sensor is not shorted to supply voltage
- 4If the fault remains, have a workshop replace the gas temperature sensor and check the wiring
Symptome, die Sie bemerken können4
- The fuel level gauge does not work
- The trip computer shows an empty tank too early
- The fuel gauge drops to zero although there is fuel in the tank
- The gas level gauge does not work
Was der Fehler beeinflussen kann1
- The fuel level is set to zero
