Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical shorts during repairs.

2. Access the Fuel Sender Unit

a. Remove the rear seat cushion (if applicable) to access the fuel tank access panel.
b. Unscrew the access panel and disconnect any wiring harnesses.
c. Carefully pull up the fuel sender unit from the tank, ensuring no fuel is spilled.

3. Inspect and Test the Fuel Sender Unit

a. Check the float mechanism of the fuel sender for any obstructions or damage.
b. Use a multimeter to measure the resistance across the sender unit terminals; compare readings with manufacturer specifications (typically 0-90 ohms).
c. If faulty, replace the fuel sender unit.

4. Reassemble Components

a. Reinstall the fuel sender unit into the tank, ensuring it is seated properly.
b. Reconnect any wiring harnesses and secure the access panel back in place.
c. Reinstall the rear seat cushion.

5. Reconnect Battery and Test

Reconnect the battery and start the vehicle.
Monitor the fuel gauge for proper function and stability.
