Solution
1. Preparation
  • Gather tools: OBD-II scanner, multimeter, socket set, and wiring diagram for the vehicle.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Check and Replace Fuse
  • Locate the fuse box in the vehicle (refer to owner's manual for exact location).
  • Remove the fuse for the fuel gauge (check the fuse diagram).
  • Inspect the fuse; if blown, replace it with a new fuse of the same amperage.
  • Reconnect the battery and check if the fuel gauge operates correctly.
3. Inspect Wiring and Connectors
  • Remove the rear seats or access panel to reach the fuel sender connector.
  • Visually inspect the wiring harness for any signs of wear, corrosion, or damage.
  • Ensure the connector is securely attached; clean any corrosion found on terminals.
  • If damaged, replace the wiring harness or connectors as necessary.
4. Test Fuel Level Sensor
  • Disconnect the fuel level sensor connector at the fuel tank.
  • Use a multimeter to measure the resistance across the sensor terminals while moving the float manually.
    • Resistance should change smoothly as the float moves from empty to full.
  • If resistance readings are not within specifications, replace the fuel level sensor.
5. Reassemble and Test
  • Reinstall any removed components and ensure all connections are secure.
  • Reconnect the battery.
  • Start the vehicle and check if the fuel gauge operates correctly.
