Solution
1. Preparation
  • Gather tools and parts required.
  • Disconnect the battery to ensure safety.
  • Ensure the vehicle is on a flat surface and the fuel tank is as empty as possible.
2. Access the Fuel Sender Unit
  • Tools Required: Socket set, screwdrivers
  • Remove the rear seat or access panel to reach the fuel tank.
  • Unscrew and remove the fuel pump access cover.
3. Remove the Fuel Sender Unit
  • Disconnect the electrical connector from the fuel sender unit.
  • Carefully unscrew the locking ring holding the fuel sender in place.
  • Remove the fuel sender unit from the tank.
4. Inspect and Test the Fuel Sender Unit
  • Tools Required: Multimeter
  • Measure the resistance across the sender unit terminals; it should change smoothly as the float moves.
  • If resistance values are outside the manufacturer specifications, replace the fuel sender unit.
5. Reinstallation
  • Install the new or repaired fuel sender unit back into the tank.
  • Secure the locking ring and reconnect the electrical connector.
  • Reattach the access cover and the rear seat.
6. Reconnect Battery and Test
