Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the vehicle battery to ensure safety during repairs.

Tools Required:

  • OBD-II scanner
  • Multimeter
  • Socket set
  • Torque wrench
  • Screwdrivers
2. Inspect Wiring and Connections
  • Remove the rear seat cushion to access the fuel tank access panel.
  • Unplug the fuel level sending unit connector.
  • Check for any corrosion or damage to the connector and wiring.

Safety Warning: Ensure the vehicle is on a level surface and the fuel tank is not full to minimize risk.

3. Test Fuel Level Sending Unit
  • Use the multimeter to measure resistance across the fuel level sending unit terminals.
    • Resistance should vary from approximately 0 to 90 ohms as the float moves.
  • If resistance is not within specifications, replace the fuel level sending unit.
4. Replace Fuel Level Sending Unit (if necessary)
  • Remove the fuel tank access panel.
  • Disconnect the fuel lines and electrical connectors from the sending unit.
  • Unscrew the locking ring and remove the sending unit from the tank.
  • Install the new sending unit by reversing the removal steps.

Torque Value: Ensure the locking ring is tightened to the manufacturer's specifications (refer to the service manual).

5. Reassemble and Test
  • Reconnect the fuel tank access panel and seat cushion.
  • Reconnect the battery.
  • Start the vehicle and check the fuel gauge operation to ensure it is functioning properly.
