Hva betyr feilkoden?
The control module monitors the sensor in the right half of the tank. If the sensor has an open circuit or is shorted to battery voltage, the signal may be missing or too high. The fault is intermittent: it has occurred before but may not be present now. The fuel gauge may then stop working.
