Solution
1. Preparation
  • Gather tools and parts: OBD-II scanner, multimeter, socket set, replacement fuel level sensor (if needed).
  • Ensure the vehicle is parked on a level surface.
  • Disconnect the battery to prevent electrical shock.
2. Inspect Fuel Level Sending Unit
  • Tools Required: Socket set
  • Locate the access panel under the rear seat or trunk to reach the fuel pump assembly.
  • Remove the access panel and disconnect the harness from the fuel pump.
  • Unscrew and remove the fuel pump assembly to access the fuel level sending unit.
3. Test Fuel Level Sensor
  • Tools Required: Multimeter
  • Connect the multimeter probes to the terminals of the fuel level sensor.
  • Move the float arm manually and observe the resistance change on the multimeter.
  • Compare the readings to the manufacturer's specifications (typically between 0-90 ohms).
4. Replace Fuel Level Sensor (if necessary)
  • Tools Required: Socket set, new fuel level sensor
  • If the sensor is defective, carefully remove it from the fuel pump assembly.
  • Install the new fuel level sensor, ensuring it is seated properly.
  • Reassemble the fuel pump assembly and reconnect all harnesses.
5. Reassemble and Test
  • Reattach the access panel securely.
  • Reconnect the battery and start the vehicle.
  • Test the gas gauge by filling the tank and observing the gauge behavior.
