Solution

1. Preparation

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

Tools Required:

OBD-II scanner
Multimeter
Socket set
Torque wrench
Screwdriver set

2. Inspect and Replace the Fuel Gauge Fuse

Locate the fuse box (usually under the dashboard on the driver's side).
Identify the fuse for the fuel gauge using the diagram on the fuse box cover.
Remove the fuse and inspect it. Replace with a new fuse of the same amperage if blown.

3. Access the Fuel Sender Unit

Lift the rear seat or remove the trunk lining to access the fuel tank access panel.
Remove the panel carefully using a screwdriver or socket set.
Disconnect the wiring harness connected to the fuel sender unit.

4. Test the Fuel Sender Unit

Use a multimeter to measure the resistance of the fuel sender unit. Refer to the vehicle's service manual for the correct resistance values.
If the resistance is out of spec, replace the fuel sender unit.

5. Reinstall Components

If the fuel sender unit was replaced, install the new unit by reversing the removal steps.
Ensure all connections are secure and there are no leaks.
Reattach the access panel and seat or trunk lining.

6. Reconnect Battery and Test

Reconnect the vehicle battery.
Start the vehicle and observe the fuel gauge to ensure it operates correctly.
