Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery cable to prevent electrical shock.

2. Replace Faulty Components

Sub-steps:
1. Identify and replace faulty sensors (e.g., oxygen sensor, MAF sensor):
  - Remove electrical connector.
  - Unbolt the sensor and replace it with a new component.
  - Reconnect the electrical connector.
2. Change spark plugs and ignition coils if indicated:
  - Remove the engine cover (if applicable).
  - Unscrew and remove old spark plugs.
  - Install new spark plugs to the manufacturer's torque specification (usually around 13 ft-lbs).
  - Replace ignition coils as necessary.
3. Inspect and replace the gas cap if damaged or not sealing properly:
  - Unscrew the old gas cap and replace it with a new one.

3. Clear Codes and Reconnect Battery

Reconnect the negative battery cable.
Use the OBD-II scanner to clear any stored error codes in the vehicle’s computer.

4. Test Drive

Conduct a test drive for at least 10-15 minutes to allow the vehicle's systems to reset and monitor for the return of the check engine light.
