Solution

1. Preparation

Gather necessary tools and parts.
Ensure the car is parked on a level surface and turn off the engine.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Error Codes

Sub-step 1: Using the OBD-II scanner, clear the error codes after noting them down.
Sub-step 2: Reconnect the battery terminal.
Sub-step 3: Start the engine and observe if the check engine light returns.

3. Perform Required Repairs

Sub-step 1: If specific codes indicate a faulty component (e.g., O2 sensor, mass air flow sensor), replace the part.
- For example, to replace an O2 sensor:
  - Use a wrench to disconnect the sensor.
  - Install the new sensor and tighten to manufacturer specifications (usually around 30 lb-ft).
Sub-step 2: If spark plugs are worn, replace them:
- Remove the ignition coils by unscrewing any retaining bolts.
- Pull out the old spark plugs using a spark plug socket.
- Install new spark plugs, ensuring they are gapped correctly (typically around 0.030-0.035 inches).
- Reattach ignition coils and secure with bolts.

4. Final Checks

Sub-step 1: Recheck all connections and components to ensure everything is secure.
Sub-step 2: Start the engine again and let it idle, checking for any abnormal sounds or leaks.
Sub-step 3: Perform a test drive to ensure the vehicle operates smoothly and the check engine light does not reappear.
