Solution
1. Preparation
  • Gather tools and parts required.
  • Disconnect the negative battery terminal to ensure safety during repairs.
2. Access the Fuel Sender Unit
  • Remove the rear seat cushion (if applicable) to access the fuel tank access panel.
  • Unscrew the access panel and lift it to expose the fuel sender unit.
3. Inspect and Test the Fuel Sender Unit
  • Disconnect the wiring harness from the fuel sender unit.
  • Use a multimeter to measure the resistance of the sender unit. It should vary as you move the float arm.
    • If the resistance is not within specification (typically between 0-90 ohms), the sender unit may need replacement.
  • Inspect the float arm for any signs of damage or fuel saturation.
4. Replace the Fuel Sender Unit (if necessary)
  • If the fuel sender is faulty, remove it by unscrewing the locking ring and carefully lifting the unit out of the tank.
  • Install the new fuel sender unit, ensuring it is positioned correctly and securely fastened.
  • Reconnect the wiring harness to the new sender unit.
5. Reassemble and Test
  • Reinstall the access panel and rear seat cushion.
  • Reconnect the negative battery terminal.
  • Start the vehicle and check if the fuel gauge operates correctly.
