Solution
1. Preparation
  • Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, wiring diagram (if available).
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Remove Instrument Cluster
  • Remove the dashboard trim surrounding the instrument cluster using a trim removal tool.
  • Unscrew and remove the instrument cluster from the dashboard.
  • Disconnect the electrical connectors at the back of the cluster.
3. Inspect and Test Fuel Level Sending Unit
  • Tools Required: Multimeter.
  • Remove the fuel pump assembly from the fuel tank.
  • Use the multimeter to measure resistance across the sending unit terminals.
    • Expected resistance should change as the float moves; typically, it ranges from about 0 to 90 ohms.
  • If the resistance is outside the expected range, replace the fuel level sending unit.
4. Reinstall Components
  • Reinstall the fuel pump assembly back into the fuel tank, ensuring all seals are properly seated.
  • Reconnect the instrument cluster to the dashboard and secure it with screws.
  • Reattach the dashboard trim.
5. Reconnect Battery and Test
  • Reconnect the negative battery terminal.
  • Start the vehicle and check if the fuel gauge functions correctly.
