Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Disconnect the negative battery terminal to ensure safety.
  • Allow the fuel system to depressurize by removing the fuel pump fuse and starting the engine until it stalls.
2. Access the Fuel Level Sending Unit
  • Tools Required: Socket set
  • Remove the rear seat or access panel to reach the fuel tank.
  • Unbolt the fuel tank access cover and remove it carefully.
3. Inspect the Fuel Level Sending Unit
  • Disconnect the electrical connector from the fuel level sending unit.
  • Remove the sending unit from the fuel tank by unscrewing it or unclipping it.
  • Inspect the float arm for free movement and check the resistance using a multimeter. The resistance should vary smoothly as the float moves.
4. Replace the Fuel Level Sending Unit (if necessary)
  • If the sending unit is faulty, install a new fuel level sending unit.
  • Tools Required: Torque wrench
  • Ensure the float moves freely and there are no blockages.
  • Reconnect the electrical connector securely.
5. Reassemble and Test
  • Reinstall the fuel tank access cover and securely bolt it down.
  • Reconnect the negative battery terminal.
  • Reinstall the rear seat or access panel.
  • Start the vehicle and check the fuel gauge operation.
