Fuel Level Sensor (G), Checking

Fuel Level Sensor (G), Checking

Special tools, testers and auxiliary items required

• Multimeter (V.A.G 1526D)

• Connector Test Set (V.A.G 1594C)

Procedure






- Remove right seat frame in 2nd row.

Risk of injury.

• Wear safety gloves.

- Cut the floor covering along the perforation - arrows - on the right side with a carpet knife - 1 -.

- Fold the floor covering to the side - arrow -.






- Remove nuts - 1 to 4 - and remove the right locking flange cover.

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






- Connect multimeter between terminals - 2 and 3 - to measure resistance.






Fuel level sensor (G) installed:

• Sensor at lower stop: 863 to 960 ohms.

• Sensor at upper stop: 67 to 86 ohms.

• If measured value is 0 ohms there is a short circuit. If measured value is infinity there is and open circuit in the wiring.

• To check resistance values "tank full" or "tank empty", the fuel level sensor must be removed and the floater of the sensor must be placed in upper or lower end position. Refer to => [ Fuel Level Sensor (G) ] Fuel Level Sensor (G).

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

Fuel level sensor removed:

• Sensor at lower stop: Approximately 990 ohms.

• Sensor at upper stop: Approximately 51 ohms.

Assemble in reverse order of disassembling. Note the following:

- Install locking flange cover.

- Install the frame into the floor covering. Refer to the Electronic Parts Catalog (ETKA)

- Install right seat frame in 2nd row.
