Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine turned off.
Disconnect the battery to prevent any electrical issues while working on the vehicle.

2. Scanning and Interpreting Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port, usually located under the dashboard.
Turn the ignition to the "ON" position without starting the engine.
Record the error codes displayed on the scanner and consult the vehicle’s service manual or a reliable database for code interpretations.

3. Addressing Identified Issues

If codes indicate a specific fault (e.g., faulty sensors, catalytic converter, etc.):
- Remove and replace the faulty component, following manufacturer specifications for torque and installation.
- Example: For a faulty oxygen sensor, disconnect the electrical connector, unscrew the sensor, and install the new one, ensuring proper alignment.
If the gas cap was loose:
- Tighten the gas cap until it clicks or replace it if damaged.

4. Resetting the Check Engine Light

After repairs, reconnect the battery.
Use the OBD-II scanner to clear the error codes.
Start the engine and monitor if the check engine light turns off after a few minutes of operation.
