Hva betyr feilkoden?
The code relates to the fuel level sensor in the left half of the tank. With the engine running, the control module registers that there is fuel in that half but that the level does not change, and the code is set. The fault is intermittent, meaning it has occurred before but may not be present now. The fuel gauge does not work properly, and the trip computer may show the tank as empty too early.
