Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the vehicle's battery to prevent electrical shock.
  • Ensure the vehicle is on a level surface and secured with wheel chocks.
2. Inspect and Replace Fuse
  • Locate the fuse box according to the owner's manual.
  • Check the fuel gauge fuse (usually labeled) and replace it if blown.
  • Reconnect the battery and test the gauge.
3. Check Wiring and Connections
  • Remove the fuel tank access panel (if applicable) or lower the fuel tank to access the sending unit.
  • Inspect the wiring harness and connector for damage, corrosion, or loose connections.
  • Repair or replace any damaged wiring or connectors.
4. Test Fuel Sending Unit
  • Use a multimeter to measure the resistance of the fuel sending unit. (Specifications typically range from 0 to 90 ohms.)
  • If the resistance is outside the required range, replace the fuel sending unit.
  • To replace, disconnect the sending unit connector, remove retaining screws, and carefully lift the unit out of the tank.
5. Reassemble Components
  • Reinstall the sending unit and ensure all connections are secure.
  • Reattach the fuel tank (if removed) and any access panels.
  • Reconnect the battery.
