Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to ensure safety while working on electrical components.
2. Access the Fuel Level Sending Unit
  • Tools Required: Socket set, screwdrivers, safety glasses, gloves.

  • Unbolt and lift the fuel tank access cover to gain access to the fuel level sending unit.
3. Inspect and Test the Fuel Level Sending Unit
  • Disconnect the electrical connector from the fuel level sending unit.
  • Use a multimeter to check the resistance of the sending unit. It should vary smoothly as the float moves.
  • If the resistance is stuck or erratic, replace the sending unit.
4. Check Wiring and Connections
  • Inspect the wiring harness for any visible damage, fraying, or corrosion at connection points.
  • Clean any corroded connectors using an electrical contact cleaner.
  • Repair or replace damaged wires as necessary.
5. Reassemble and Test
