Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle's battery to prevent electrical shock.
Allow the vehicle to cool down if it has been running.

2. Remove the Instrument Cluster

Remove the dashboard trim panel surrounding the instrument cluster using a trim removal tool.
Unscrew the bolts securing the instrument cluster using a socket set.
Gently pull the instrument cluster out and disconnect the electrical connectors at the back.

3. Inspect and Test the Fuel Gauge

Check for any visible damage to the circuit board of the instrument cluster.
If equipped, run a self-test of the instrument cluster to ensure all gauges respond appropriately.
If the fuel gauge remains faulty, proceed to replace the fuel level sender.

4. Replace the Fuel Level Sender

Access the fuel tank by removing the rear seat or trunk panel, depending on model configuration.
Disconnect the fuel pump wiring harness and remove the retaining ring using a fuel pump removal tool.
Carefully lift out the fuel pump assembly, noting the orientation for reinstallation.
Remove the old fuel level sender from the assembly and replace it with a new one.
Reinstall the fuel pump assembly into the tank and secure it with the retaining ring.

5. Reassemble and Test

Reconnect the electrical connectors to the instrument cluster.
Reinstall the instrument cluster and dashboard trim panel.
Reconnect the vehicle's battery.
Start the vehicle and verify that the fuel gauge operates correctly.
