Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace the Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Use a fuse puller or pliers to remove the fuel gauge fuse.
Inspect the fuse for continuity; replace it if it’s blown.
Reconnect the fuse and check if the gauge functions properly.

3. Access the Fuel Sender Unit

Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the battery again for safety.
Remove the rear seat or access panel to reach the fuel sender assembly.
Disconnect the wiring harness from the fuel sender unit.

4. Test the Fuel Sender Unit

Use a multimeter to measure the resistance across the sender terminals.
Compare the readings to the manufacturer specifications (typically found in the service manual).
If the readings are out of specification, replace the fuel sender unit.

5. Reassemble and Test

Reinstall the fuel sender unit and reconnect the wiring harness.
Reconnect the battery.
Start the vehicle and monitor the fuel gauge for proper operation.
