Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is off.
  • Disconnect the battery before beginning any electrical work.
2. Inspect and Repair Fuel Level Sensor
  1. Locate the Fuel Level Sensor:

    • Access the fuel tank area by removing the rear seat or trunk panel as needed.
    • Identify the fuel level sensor connected to the fuel pump.
  2. Remove the Fuel Level Sensor:

    • Disconnect the electrical connector from the sensor.
    • Unscrew or unclip the sensor from the fuel tank using a socket set.
    • Carefully remove the sensor from the tank.
  3. Test the Fuel Level Sensor:

    • Use a multimeter to measure resistance across the sensor terminals.
    • Compare the readings to the manufacturer specifications; replace if readings are out of range.
  4. Clean and Reinstall:

    • Clean any corrosion from the connector and harness.
    • Reinstall the fuel level sensor by reversing the removal steps and ensuring it is securely fitted.
3. Recalibrate the Fuel Gauge
  1. Reconnect the Battery:

    • Reconnect the battery terminals ensuring a secure connection.
  2. Access Calibration Settings:

    • Turn on the vehicle and access the settings menu through the infotainment system.
