Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the vehicle's battery to ensure safety during repairs.
  • Ensure the vehicle is parked on a level surface.
2. Access the Fuel Sender Unit
  • Remove the rear seat or access panel to reach the fuel pump assembly.
  • Disconnect the wiring harness from the fuel pump assembly.
  • Remove the retaining ring securing the fuel pump assembly using a specialized tool or a flathead screwdriver.
3. Inspect and Test the Fuel Sender Unit
  • Carefully lift out the fuel pump assembly to access the fuel sender unit.
  • Use a multimeter to measure the resistance of the sender unit while moving the float arm. The resistance should change smoothly between the minimum and maximum values (usually around 0 to 90 ohms).
  • If the resistance is erratic or does not change, replace the fuel sender unit.
4. Replace the Fuel Sender Unit (if necessary)
  • If replacement is required, install the new fuel sender unit by reversing the removal steps.
  • Ensure the float moves freely and is not obstructed.
  • Reconnect the wiring harness and secure the assembly with the retaining ring.
5. Reassemble and Test
  • Reinstall the rear seat or access panel.
  • Reconnect the vehicle battery.
  • Start the vehicle and verify that the fuel gauge reads accurately.
