Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Disconnect the negative battery cable to prevent electrical shorts.
2. Access the Fuel Level Sending Unit
  • Tools Required: Socket set, screwdrivers, safety glasses, gloves.
  • Remove the rear seat or access panel to reach the fuel tank.
  • Disconnect any electrical connectors and fuel lines carefully.
  • Remove the fuel tank access cover using the appropriate socket.
3. Inspect and Test the Fuel Level Sending Unit
  • Remove the fuel level sending unit from the tank.
  • Use a multimeter to check the resistance across the sending unit terminals while moving the float arm. The resistance should change smoothly between specified values (check the service manual for exact specifications).
  • If the resistance is not within specification, replace the fuel level sending unit.
4. Reassemble and Reconnect
  • Reinstall the fuel level sending unit and secure it properly.
  • Reconnect the fuel lines and electrical connectors.
  • Replace the fuel tank access cover.
  • Reinstall the rear seat or access panel.
5. Final Checks
  • Reconnect the negative battery cable.
  • Turn on the ignition and check for any leaks around the fuel lines and sending unit.
