Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Address Error Codes
  • Sub-step 1: Review the OBD-II codes retrieved. Research their meanings and prioritize based on severity.
  • Sub-step 2: Clear the codes using the OBD-II scanner and take the vehicle for a test drive to see if the light reappears.
3. Repair Specific Issues
  • Sub-step 1: If codes indicate a faulty oxygen sensor, locate the sensor and remove it using a socket wrench.
  • Sub-step 2: Install the new oxygen sensor, ensuring it is tightened to the manufacturer’s torque specifications (usually around 30 lb-ft).
  • Sub-step 3: If the issue is related to spark plugs, remove the old plugs using a spark plug socket, inspect the ignition coils, and replace plugs with OEM equivalents, torquing to the specified value (typically 13 lb-ft).
4. Reassemble and Reconnect
  • Reinstall any components removed during diagnosis and repairs.
  • Reconnect the battery terminals, ensuring they are tightened securely.
5. Final Checks
  • Start the engine and monitor for any irregularities.
  • Ensure that the check engine light is no longer illuminated.
