Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Address Error Codes

Use the OBD-II scanner to retrieve error codes.
Research the codes to determine specific faulty components (e.g., O2 sensors, mass airflow sensor).

3. Inspect and Replace Components

If the gas cap is faulty, replace it with a new one.
For faulty sensors, remove the defective component:
- Oxygen Sensor Replacement:
  - Disconnect the wiring connector.
  - Use an O2 sensor socket to unscrew the old sensor.
  - Install the new sensor and reconnect the wiring.
If spark plugs are worn:
- Remove the ignition coils.
- Use a spark plug socket to remove old plugs, inspect for wear, and install new plugs with a torque of 13 lb-ft.

4. Reset Check Engine Light

Reconnect the battery.
Use the OBD-II scanner to clear the error codes and reset the check engine light.
