Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shorts.
  • Ensure the vehicle is parked on a level surface.
2. Remove Instrument Cluster
  • Remove any trim panels surrounding the instrument cluster using a trim removal tool.
  • Unscrew the instrument cluster screws (typically Torx or Phillips) and carefully pull the cluster out.
  • Disconnect the wiring harness from the back of the cluster.
3. Inspect and Test
  • Check the wiring harness for any signs of corrosion or damage, repairing as necessary.
  • Use a multimeter to test the fuel level sending unit’s resistance. It should vary between 0 to 90 ohms when the float moves.
  • If the sending unit is faulty, proceed to replace it.
4. Replace Fuel Level Sending Unit (if necessary)
  • Access the fuel tank by removing the rear seat or opening the trunk (depending on the model).
  • Disconnect the fuel pump wiring harness and remove the fuel pump assembly.
  • Replace the fuel level sending unit and reassemble the fuel pump assembly.
  • Reconnect the wiring harness and ensure all connections are secure.
5. Reinstall Instrument Cluster
  • Reconnect the instrument cluster wiring harness.
  • Position the cluster back into the dashboard and secure with screws.
  • Reattach any trim panels that were removed.
6. Reconnect Battery and Test
  • Reconnect the negative battery terminal.
  • Turn on the ignition and check if the fuel gauge operates correctly.
  • Perform a test drive to ensure the gauge reflects accurate fuel levels.
