Solution

1. Preparation

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

2. Retrieve and Analyze Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn on the ignition (do not start the engine) and read the error codes.
Document any codes and refer to the service manual for their meanings.

3. Address Identified Issues

If codes indicate a specific sensor failure (e.g., O2 sensor, MAF sensor):
- Remove the faulty sensor using a socket set.
- Install the new sensor and tighten to the manufacturer's specified torque.
For gas cap issues:
- Replace the gas cap with a new one if it's damaged or not sealing properly.
If a vacuum leak is identified:
- Replace any damaged hoses and ensure all connections are secure.

4. Clear Codes and Test

Use the OBD-II scanner to clear the error codes from the system.
Reconnect the negative battery cable.
Start the engine and allow it to reach operating temperature.

5. Test Drive

Drive the vehicle for a short distance under various conditions (stop-and-go, highway speeds) to monitor performance.
Observe if the check engine light remains off during and after the test drive.
