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

Tools Required:

  • OBD-II scanner
  • Multimeter
  • Socket set
  • Screwdrivers
  • Safety goggles
  • Torque wrench
2. Access the Fuel Sending Unit
  • Remove the rear seat or trunk cover to access the fuel tank access panel.
  • Use a socket set to remove the bolts securing the access panel.
  • Carefully lift the panel to expose the fuel sending unit.
3. Inspect the Fuel Sending Unit
  • Disconnect the electrical connector from the fuel sending unit.
  • Using a multimeter, measure the resistance across the terminals of the sending unit; it should vary smoothly as the float is moved.
  • If the resistance is constant or out of specification, the sending unit may need replacement.
4. Replace the Fuel Sending Unit (if necessary)
  • If replacement is needed, carefully remove the old sending unit by unscrewing it from the tank.
  • Install the new sending unit according to the manufacturer's specifications.
  • Reconnect the electrical connector to the new sending unit.
5. Reassemble and Test
  • Replace the access panel and secure it with the bolts.
  • Reinstall the rear seat or trunk cover.
  • Reconnect the vehicle battery.
  • Start the vehicle and check if the fuel gauge is functioning correctly.
