Solution
1. Preparation
  • Gather tools: OBD-II scanner, multimeter, socket set, and a dipstick.
  • Ensure the vehicle is parked on a level surface and the ignition is off.
  • Disconnect the negative battery terminal to ensure safety.
2. Remove Fuel Sending Unit
  • Sub-step 1: Access the fuel tank by removing the rear seat or trunk panel, depending on the model year.
  • Sub-step 2: Disconnect the fuel lines from the sending unit carefully to avoid spillage.
  • Sub-step 3: Unscrew the retaining ring or bolts securing the sending unit and lift it out of the tank.
3. Inspect and Test Sending Unit
  • Sub-step 1: Use a multimeter to check the resistance of the sending unit. It should vary as the float moves.
  • Sub-step 2: If the resistance is outside the specifications, replace the sending unit.
  • Sub-step 3: Inspect the float for any signs of damage or fuel intrusion which would cause it to sink.
4. Reassemble and Test
  • Sub-step 1: Reinstall the sending unit into the fuel tank and secure it with the retaining ring or bolts.
  • Sub-step 2: Reconnect the fuel lines and ensure all connections are tight.
  • Sub-step 3: Reconnect the battery terminal and start the vehicle to check for proper gauge operation.
