Solution
1. Preparation
  • Gather tools and parts listed below.
  • Ensure the vehicle is parked on a level surface and the engine is off.
2. Retrieve and Analyze Error Codes
  • Connect the OBD-II scanner to the vehicle’s diagnostic port (usually located under the dashboard).
  • Turn on the ignition without starting the engine.
  • Retrieve and note down any error codes for further analysis.
3. Inspect and Replace Faulty Components
  • Based on retrieved error codes, identify the faulty component (e.g., oxygen sensors, mass airflow sensor, spark plugs).
  • For oxygen sensors:
    • Use a socket wrench to remove the sensor from the exhaust pipe.
    • Install the new sensor and torque to manufacturer specifications (usually around 30 lb-ft).
  • For spark plugs:
    • Remove the ignition coil by disconnecting the electrical connector and unbolting it.
    • Unscrew the old spark plug using a spark plug socket.
    • Install new spark plugs, torquing to about 15 lb-ft.
4. Reset the Check Engine Light
  • After repairs, use the OBD-II scanner to clear the error codes.
  • Turn off the ignition and disconnect the scanner.
5. Test Drive
  • Start the engine and allow it to idle for a few minutes.
  • Take the vehicle for a test drive to ensure the check engine light does not reappear and the engine operates normally.
