Solution
1. Preparation
  • Gather tools and parts.
  • Disconnect the battery to ensure safety during repairs.
2. Access the Fuel Level Sensor
  • Remove the rear seat cushion to access the fuel tank access panel.
  • Unscrew and remove the access panel to expose the fuel tank assembly.
3. Inspect the Fuel Level Sensor
  • Disconnect the electrical connector from the fuel level sensor.
  • Use a multimeter to test the sensor’s resistance by measuring between the terminals.
    • Expected resistance: 0-90 ohms (varies with fuel level).
  • If readings are outside this range, proceed to replacement.
4. Replace the Fuel Level Sensor (if faulty)
  • Remove the retaining ring that holds the fuel level sensor in place.
  • Carefully pull the fuel level sensor out from the tank.
  • Install the new fuel level sensor by reversing the removal steps, ensuring it is seated correctly and the retaining ring is securely fastened.
5. Reassemble and Test
  • Reconnect the electrical connector to the fuel level sensor.
  • Replace the access panel and rear seat cushion.
  • Reconnect the battery.
