Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to prevent electrical shorts.
Allow the vehicle to cool down before working on the fuel system.

2. Access the Fuel Sending Unit

Sub-steps:
1. Remove the rear seats or the access panel if applicable to reach the fuel pump access cover.
2. Unscrew the access cover using a socket set to expose the fuel sending unit.

3. Inspect and Test the Fuel Sending Unit

Sub-steps:
1. Disconnect the wiring harness from the fuel sending unit.
2. Use a multimeter to measure the resistance of the fuel level sensor; it should vary with the fuel level.
3. If the resistance is out of range, replace the fuel sending unit.

4. Replace the Fuel Sending Unit (if needed)

Sub-steps:
1. Remove the old fuel sending unit by unscrewing it from the tank.
2. Install the new fuel sending unit, ensuring the O-ring is properly seated.
3. Reconnect the wiring harness and secure the access cover with screws.

5. Reconnect the Battery and Test

Sub-steps:
1. Reconnect the battery terminals, ensuring they are tight and secure.
2. Start the vehicle and check the fuel gauge operation; it should reflect the accurate fuel level.
