Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to ensure safety before starting work.
2. Address Error Codes
  • Using the OBD-II scanner, read the trouble codes.
  • Research the codes to understand the underlying issues they indicate.
3. Inspect and Replace Components
  • If codes indicate a faulty sensor (e.g., oxygen sensor, mass air flow sensor), locate the component.
  • Remove the sensor by unscrewing bolts or unclipping connectors, as necessary.
  • Install the new sensor by reversing the removal process. Ensure connections are secure.
4. Check and Replace Spark Plugs (if necessary)
  • Remove the ignition coils by unbolting them from the engine.
  • Pull out the spark plugs using a spark plug socket.
  • Inspect plugs for wear; replace if needed with OEM recommended spark plugs.
  • Reinstall the new spark plugs and ignition coils, ensuring proper torque (typically around 13-15 ft-lb for plugs).
5. Clear Codes and Test Drive
  • Reconnect the negative battery terminal.
  • Use the OBD-II scanner to clear the trouble codes.
  • Test drive the vehicle to see if the check engine light remains off and the vehicle operates smoothly.
