Solution
1. Preparation
  • Tools Required: OBD-II scanner, multimeter, socket set, screwdrivers.
  • Ensure the vehicle is parked on a level surface and the ignition is off before starting the repair.
2. Inspect and Replace the Fuel Gauge Fuse
  • Locate the fuse box (refer to the owner's manual for the exact location).
  • Remove the cover and identify the fuse for the fuel gauge.
  • Use a multimeter to check for continuity in the fuse.
  • If the fuse is blown, replace it with a fuse of the same amperage.
3. Check Wiring and Connectors
  • Inspect the wiring harness connected to the fuel level sending unit located in the fuel tank.
  • Disconnect the connector and check for bent pins or corrosion.
  • Clean any corrosion with electrical cleaner and ensure a snug fit when reconnecting.
4. Test the Fuel Level Sending Unit
  • Access the fuel level sending unit by removing the rear seat or accessing the fuel tank (depending on the model).
  • Disconnect the wiring from the sending unit.
  • Use a multimeter to measure resistance; it should vary with the float level.
  • If the resistance does not change, replace the fuel level sending unit.
5. Reassemble and Test
  • Reassemble any components removed during the inspection.
  • Reconnect the battery and start the vehicle.
  • Check if the fuel gauge operates correctly.
