- If measured value is 0 Ohm there is a short circuit. If measured value is infinite Ohms there is and open circuit in the wiring.
- To check resistance values "tank full" or "tank empty", the fuel delivery unit must be removed and the floater of the sensor must be placed in upper or lower end position.
- With fuel level sensor G removed, the following values are obtained because of the greater deflection of the floater arm:
