Solution
1. Preparation
  • Gather tools and materials needed for the repair.
  • Disconnect the battery to ensure safety while working on electrical components.
  • Tools Required: OBD-II scanner, socket set, multimeter, torque wrench.
2. Address Error Codes
  • Use the OBD-II scanner to read the error codes and document them.
  • Clear the codes and perform a test drive to see if they return.
  • If codes reappear, proceed to address the specific issues indicated (e.g., replacing a faulty sensor).
3. Inspect and Replace Components
  • Based on the diagnostic results, remove and replace any defective components (e.g., oxygen sensors, spark plugs).
  • For Spark Plug Replacement:
    • Remove the ignition coil using a socket set.
    • Unscrew the old spark plug and replace it with a new one.
    • Torque to manufacturer specifications (typically around 15-20 ft-lbs).
4. Reassemble and Reconnect
  • Reattach any components removed during inspection or replacement.
  • Reconnect the battery terminals securely.
5. Final Checks
  • Start the engine and let it idle, checking for any unusual sounds or warning lights.
  • Use the OBD-II scanner to ensure no new trouble codes appear.
