Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, vacuum gauge, torque wrench, and general hand tools.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Address Trouble Codes

Connect the OBD-II scanner and retrieve the trouble codes.
Research the codes to determine the faulty components or systems.
For example, if the code indicates a faulty oxygen sensor, proceed to the next steps.

3. Replace Faulty Components

If the gas cap is faulty:
- Remove the old gas cap and replace it with a new one.
If an oxygen sensor or MAF sensor is faulty:
- Disconnect the battery (negative terminal).
- Remove the faulty sensor using the appropriate socket.
- Install the new sensor, ensuring it is securely connected.
- Reconnect the battery.

4. Inspect and Repair Vacuum Leaks

Visually inspect all vacuum hoses for cracks or disconnections.
Use a vacuum gauge to check for leaks.
Replace any damaged hoses with new ones, ensuring proper connections.

5. Clear Codes and Test Drive

Use the OBD-II scanner to clear the trouble codes after repairs are completed.
Start the engine and allow it to reach operating temperature.
Take the vehicle for a test drive to ensure that the check engine light does not reappear.
