Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety during repairs.

2. Inspect Fuel Gauge Fuse

Locate the fuse box (refer to the owner's manual for specific location).
Remove the fuel gauge fuse using a fuse puller.
Check the fuse for continuity using a multimeter. Replace if blown.

3. Access Fuel Level Sender Unit

Raise the vehicle safely using a jack and secure it with jack stands.
Remove the fuel tank access panel if applicable (consult repair manual for specific procedures).
Disconnect the electrical connector from the fuel level sender unit.

4. Test Fuel Level Sender Unit

Use a multimeter to measure the resistance of the sender unit. The resistance should change as the float moves.
If resistance is not within specifications, replace the fuel level sender unit.

5. Reassemble

Reconnect the electrical connector to the fuel level sender unit.
Replace the fuel tank access panel and secure it.
Reinstall the fuel gauge fuse into the fuse box.

6. Final Checks

Reconnect the battery.
Start the vehicle and observe the fuel gauge operation.
