Solution

1. Preparation

Gather tools and materials needed for repairs.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to reset the system.

2. Address Fault Codes

Reconnect the OBD-II scanner and note any fault codes.
Research the specific codes to determine the appropriate repairs (e.g., replace faulty sensor, repair wiring).

3. Inspect and Replace Components

Gas Cap: If the gas cap is found faulty, replace it with a new one. Ensure it clicks into place securely.
Sensors: If a specific sensor (e.g., oxygen sensor, mass airflow sensor) is faulty, follow these steps:
- Disconnect the electrical connector.
- Remove the sensor using a socket or wrench.
- Install the new sensor and reconnect the electrical connector.

4. Clear Codes and Test

After repairs, use the OBD-II scanner to clear the fault codes.
Reconnect the negative battery terminal.
Start the engine and let it run for a few minutes to ensure the check engine light does not reappear.
