Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the vehicle battery to prevent electrical shorts during repairs.
2. Access the Fuel Level Sending Unit
  • Remove the rear seat or trunk panel to access the fuel pump assembly.
  • Disconnect the electrical connector from the fuel pump/sending unit.
  • Unscrew and remove the fuel pump assembly from the fuel tank.
3. Inspect and Test the Fuel Level Sending Unit
  • Check the float mechanism on the sending unit for free movement; it should not be stuck.
  • Use a multimeter to test the resistance of the sending unit while moving the float manually. The resistance should change smoothly between the specified range (typically 0-90 ohms).
  • If the sending unit is faulty, replace it with a new one.
4. Reassemble the Components
  • Clean the sealing surface of the fuel tank before reinstalling the pump assembly.
  • Reinstall the fuel pump assembly and securely tighten it to the manufacturer’s specifications.
  • Reconnect the electrical connector to the fuel pump/sending unit.
5. Reconnect Battery and Test
  • Reconnect the vehicle battery.
  • Start the engine and observe the fuel gauge for proper operation.
  • Test drive the vehicle to ensure the gauge reflects the correct fuel level.
