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






• The electric wires for fuel level sensor 2 are routed to the fuel pump locking flange inside the fuel tank.

- Remove the rear bench seat.

- Remove the locking flange cover - arrows -.

- Disconnect the connectors - 1 and 2 - - 2 - on the locking flange.






- Connect the multimeter for the resistance measurement between terminal - 2 - on the connector - A - and terminal - 2 - on the connector - B -.






Fuel level sensor 2 installed:

• Sensor at lower stop: approximately 290 ohms.

• Sensor at upper stop: approximately 45 ohms.

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

• To check resistance values "tank full" or "tank empty", the fuel level sensor 2 (G169) must be removed. Refer to => [ Fuel Level Sensor 2 (G169) ] Fuel Level Sensor 2 (G169) and the sensor floater must be placed in the upper or lower end position.

• With fuel gauge sensor 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 290 ohms.

• Sensor at upper stop: approximately 16 ohms.

- Connect the multimeter between terminals - 1 and 2 - on connector - A - to measure the resistance.






Fuel level sensor 2 installed or removed:

• Any sensor position: approximately 340 ohms.

Assemble in reverse order of disassembling. Note the following:

- Install the right locking flange cover. Refer to => [ Locking Flange Cover - Tightening Specifications ] Fuel Tank With Attachments Overview.

- Install the rear bench seat.
