Solution

1. Preparation

Gather tools and parts needed for repairs.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool down if it has been running.

2. Addressing Error Codes

Using the OBD-II scanner, retrieve and document the error codes.
Research the codes to determine the specific components or systems that may require attention.

3. Replace Faulty Components

If codes indicate a faulty sensor (e.g., oxygen sensor, mass airflow sensor):
- Disconnect the sensor's electrical connector.
- Remove mounting screws and take out the faulty sensor.
- Install the new sensor, ensuring proper orientation and tightness.
- Reconnect the electrical connector.

4. Repair or Replace the Gas Cap

If the gas cap is damaged or not sealing properly:
- Remove the gas cap and inspect the rubber seal for cracks or wear.
- Replace the gas cap with a new one if necessary, ensuring it clicks securely into place.

5. Clear Error Codes

Reconnect the battery terminal.
Use the OBD-II scanner to clear the error codes from the vehicle's computer.
Conduct a short test drive to see if the CEL reappears.
