Fuel Level Sensor 2 (G169), Checking
Special tools, testers and auxiliary items required
• Multimeter (V.A.G 1526E)
• Connector Test Set (V.A.G 1594C)
• Carpet knife, commercially available
Procedure
- Remove the left single seat and the left 2/3 seat bench seat cushion in the second row of seats.
Risk of injury.
• Wear protective gloves.
- Cut the floor covering along the perforation - arrows - on the left side with a carpet knife - 1 -.
- Fold carpet cut-out to side - arrow -.
- Remove the nuts - 1 to 4 - and remove left locking flange cover.
- Disconnect the electrical connector - arrow - on the left locking flange.
- 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 there and open circuit in the wiring.
• To check resistance values "tank full" or "tank empty", the fuel level sensor 2 must be removed. Refer to => [ Fuel Level Sensor (G) ] Fuel Level Sensor (G) and the sensor floater must be placed in the upper or lower end position.
• 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:
- Connect the connector - arrow - at left locking flange.
- Install the left locking flange cover. Refer to => [ Locking Flange Cover - Tightening Specifications ] Fuel Tank With Attachments With Reducing Agent Metering System Overview.
- Install the frame into the floor covering. and to the Parts Catalog.
- Install the left single seat and the left 2/3 seat bench seat cushion in the second row of seats.
