Solution
1. Preparation
  • Gather necessary tools including a socket set, multimeter, OBD-II scanner, and safety glasses.
  • Ensure the vehicle is parked on a level surface and the ignition is off.
  • Disconnect the battery to prevent any electrical shorts.
2. Access Fuel Tank
  • Remove the rear seat cushion (if applicable) to access the fuel pump access panel or drop the fuel tank.
  • If accessing through the access panel, remove the screws and carefully lift the panel.
3. Remove Fuel Sending Unit
  • Disconnect the wiring harness from the fuel sending unit carefully.
  • Remove the retaining ring or screws holding the fuel sending unit in place and lift it out of the tank.
  • Inspect the float arm and connections for any visible damage or obstruction.
4. Inspect and Replace Sending Unit (if necessary)
  • Use the multimeter to check the resistance of the fuel level sensor; replace it if it’s out of specification.
  • If replacement is necessary, install the new fuel sending unit by reversing the removal steps, ensuring the float moves freely.
5. Reassemble and Test
  • Reinstall the access panel or fuel tank securely.
  • Reconnect the battery and clear any error codes using the OBD-II scanner.
  • Start the vehicle and check the operation of the fuel gauge.
