Solution
1. Preparation
  • Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and the engine is off.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Access Fuel Sending Unit
  • Tools Required: Socket set, ratchet, screwdriver set
  • Remove the rear seat or access panel to reach the fuel tank access cover.
  • Unscrew and remove the access cover to expose the fuel sending unit.
3. Inspect and Test Fuel Sending Unit
  • Disconnect the electrical connector from the fuel sending unit.
  • Tools Required: Multimeter
  • Measure the resistance of the sending unit while moving the float arm through its range. Resistance should vary according to the float position (typically 0-90 ohms).
  • If resistance is not in the expected range, replace the fuel sending unit.
4. Check Wiring and Connections
  • Visually inspect all wiring and connectors for damage, corrosion, or loose connections.
  • Repair or replace any damaged wiring or connectors.
5. Reassemble and Test
  • Reconnect the fuel sending unit and the electrical connector.
  • Reinstall the access cover and any components removed to access the sending unit.
  • Reconnect the battery.
