Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and a flathead screwdriver.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shocks.

2. Access the Fuel Sender Unit

Step 1: Remove the rear seat or trunk lining to access the fuel tank inspection cover.
Step 2: Unscrew and remove the cover to expose the fuel sender unit.
Step 3: Disconnect the electrical connector from the fuel sender unit.

3. Inspect and Test the Fuel Sender Unit

Step 1: Remove the fuel sender unit by unscrewing the retaining screws.
Step 2: Carefully lift the sender unit out of the fuel tank.
Step 3: Use a multimeter to measure the resistance of the fuel sender unit. It should vary with the float position.
Step 4: If the resistance is out of specification, replace the fuel sender unit.

4. Reassemble and Reconnect

Step 1: Place the new or inspected fuel sender unit back into the fuel tank.
Step 2: Secure it with the retaining screws and reconnect the electrical connector.
Step 3: Replace the inspection cover and reassemble the rear seat or trunk lining.

5. Reconnect Battery and Test

Step 1: Reconnect the vehicle's battery.
Step 2: Start the engine and check the functionality of the fuel gauge.
