Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the vehicle to cool if it has been running.

2. Access the Fuel Sender Unit

Tools Required: Socket set, screwdrivers, safety glasses
Remove the rear seat or access panel to reach the fuel tank.
Disconnect any electrical connectors and remove the retaining bolts for the fuel sender unit.

3. Inspect and Test the Fuel Sender

Remove the fuel sender unit from the tank.
Inspect the float arm for any sticking or physical obstructions.
Use a multimeter to measure resistance across the terminals of the sender. It should vary between approximately 0 to 90 ohms as the float moves. If it remains constant or varies outside this range, replace the sender.

4. Replace the Fuel Sender (if necessary)

If the fuel sender is faulty, install a new fuel sender unit.
