Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working.
Allow the engine to cool down if it has been running.

2. Retrieve and Interpret Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Select the option to read codes and record any active or pending codes.
Research the codes to determine common causes and affected components.

3. Address Common Fault Codes

P0010/P0011 (Variable Valve Timing Issues)
- Remove the valve cover to inspect the VVT solenoid and timing chain.
- Replace the solenoid if faulty.
P0300-P0306 (Random and Specific Cylinder Misfires)
- Check spark plugs and ignition coils for wear.
- Replace spark plugs and coils as necessary.
P0171/P0174 (Lean Condition)
- Inspect for vacuum leaks and check the MAF sensor.
- Clean or replace the MAF sensor and repair any leaks found.

4. Clear Codes and Test

After repairs, use the scanner to clear the codes.
Reconnect the battery terminal and start the engine.
Monitor for any reoccurrence of the check engine light.

5. Final Inspection

Conduct a final visual inspection for any loose connections or components.
Test drive the vehicle to ensure normal operation and that the check engine light does not return.
