Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to prevent electrical shock.
Ensure the vehicle is parked on a level surface and the fuel tank is as empty as possible.

2. Access the Fuel Level Sensor

Tools Required: Socket set, screwdriver, pry tool.
Remove the rear seat cushion (if applicable) or access panel to reach the fuel tank.
Unbolt and remove the fuel pump module cover to access the fuel level sensor.

3. Inspect and Test the Fuel Level Sensor

Disconnect the electrical connector from the fuel level sensor.
Use a multimeter to measure the resistance of the sensor. Compare readings with specifications (typically 0-90 ohms) to determine if it is faulty.
If the sensor is faulty, proceed to replace it.

4. Replace the Fuel Level Sensor (if needed)

Remove the fuel level sensor from the fuel pump module.
Install the new fuel level sensor, ensuring it is seated properly.
Reattach the electrical connector securely.

5. Reassemble Components

Replace the fuel pump module cover and secure it with bolts.
Reinstall the rear seat cushion or access panel.
Reconnect the negative terminal of the battery.

6. Test the System

Start the vehicle and check if the fuel gauge operates correctly.
Test drive the vehicle to ensure the gauge reflects accurate fuel levels.
