Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Retrieve and Analyze Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Record any error codes and research their meanings.
Clear the codes and observe if the check engine light returns to identify intermittent issues.

3. Inspect and Replace Components

If error codes indicate specific components (e.g., oxygen sensor, mass airflow sensor):
- Remove the faulty component using the appropriate tools (socket set).
- Install the new part, ensuring it is properly seated and secured (follow torque specifications if applicable).

4. Check and Replace the Fuel Cap

Inspect the fuel cap for cracks or damage.
If defective, replace it with a new OEM fuel cap.

5. Testing and Reassembly

Reconnect the battery terminal.
Start the engine and allow it to idle; monitor for any irregularities.
Take the vehicle for a short test drive, checking for any re-illumination of the check engine light.
