Fuel Level Sensor, Checking

Fuel Level Sensor, Checking

Special tools, testers and auxiliary items required

• Hand-held multimeter (V.A.G 1526C)

• Connector test set (V.A.G 1594C)

Procedure





- Remove rear seat bench.

- Unbolt cover for right locking flange - arrows -.

- Disconnect electrical harness connector - arrow - at locking flange.





- Connect multimeter between terminal - 2 - and - 3 - for resistance measurement.





Fuel Level Sensor (G) installed:

• Sensor at lower stop: approximately 760 to 1003 ohms.

• Sensor at upper stop: approximately 70 to 105 ohms.

• If measured value is 0 ohms 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. Refer to => [ Fuel Delivery Unit ] Fuel Delivery Unit.

• With fuel gauge sender removed, the following values are obtained because of the greater deflection of the floater arm:

Fuel level sensor removed:

• Sensor at lower stop: approximately 1004 ohms.

• Sensor at upper stop: approximately 50 ohms.

Assembly is performed in the reverse order of removal, noting the following:

- Install rear seat bench.
