Fuel Level Sensor 2, Checking






Fuel Level Sensor 2, 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 - 3 - and - 4 - for resistance measurement.





Fuel Level Sensor 2 (G169) installed:

Sensor at lower stop: approximately 790 to 975 ohms.

Sensor at upper stop: approximately 50 to 86 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 level sensor 2 must be removed and the sensor floater must be placed in upper or lower end position. Refer to => [ Fuel Level Sensor 2 ] Fuel Level Sensor 2.

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

Fuel level sensor 2 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.
