Fuel Level Sensor 2 (G169), Checking

Fuel Level Sensor 2 (G169), Checking

Special tools, testers and auxiliary items required

• Multimeter (V.A.G 1526D)

• Connector Test Set (V.A.G 1594C)

Procedure






- Remove 2nd row left seat cushion.

Risk of injury.

• Wear safety gloves.

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

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






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

- Disconnect electrical harness connector - 1 - at left locking flange.






• Ignore - 2 -.

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






Fuel level sensor 2 installed:

• Sensor at lower stop: 760 to 842 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 2 must be removed and the sensor floater must be placed in upper or lower end position. Refer to => [ Fuel Level Sensor 2 (G169) ] Fuel Level Sensor 2 (G169).

• With fuel level sensor 2 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 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 2nd row left seat cushion.
