Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery (negative terminal) to prevent electrical shorts.

2. Retrieve and Interpret Codes

Use the OBD-II scanner to read error codes.
Document any codes and research their meanings in the vehicle’s service manual.

3. Address Identified Issues

Gas Cap:
- Inspect for cracks or wear; replace if damaged.
- Tighten the gas cap until it clicks.
Sensor Issues:
- If codes indicate a specific sensor failure (e.g., O2 sensor), proceed to replace that sensor.
Electrical Connections:
- Clean and secure any loose connections.
- Repair or replace damaged wiring as necessary.

4. Clear Codes and Reconnect Battery

Clear the trouble codes using the OBD-II scanner.
Reconnect the battery (positive terminal first, then the negative).

5. Test Drive

Start the engine and allow it to reach operating temperature.
Take the car for a test drive to check for any recurrence of the check engine light or symptoms.
