Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle battery to prevent electrical shorts.
Allow the vehicle to cool if it has been running.

2. Inspect Fuel Level Sensor

Tools Required: Multimeter, socket set, torque wrench.
Sub-steps:
1. Remove the rear seat or access panel to locate the fuel pump assembly.
2. Disconnect the fuel pump electrical connector.
3. Use the multimeter to measure the resistance of the fuel level sensor. It should vary with the fuel level.
4. If the reading is out of specification, proceed to replace the sensor.

3. Replace Fuel Level Sensor (if necessary)

Tools Required: Socket set, torque wrench, safety glasses, gloves.
Sub-steps:
1. Relieve fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
2. Disconnect the negative battery terminal.
3. Remove the fuel tank access cover and the fuel pump assembly retaining ring.
4. Carefully lift the fuel pump assembly out of the tank.
5. Remove the old fuel level sensor from the fuel pump assembly.
6. Install the new fuel level sensor, ensuring it is properly seated.
7. Reassemble the fuel pump assembly and secure it with the retaining ring.
8. Reconnect the electrical connector and reinstall the access cover.

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check the fuel gauge operation.
If the gauge operates normally, proceed to test drive the vehicle.
