Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Disconnect the negative battery terminal to reset the system.

2. Retrieve and Analyze Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Record any diagnostic trouble codes (DTCs) displayed on the scanner.
Research the codes to determine the potential issues.

3. Inspect and Repair Identified Issues

Based on the retrieved codes, inspect the corresponding components:
- For a misfire code, check spark plugs and ignition coils for wear or failure.
- For an oxygen sensor code, test the sensor's voltage output with a multimeter and replace if necessary.
- For EVAP codes, inspect the fuel cap and associated lines for leaks or blockages.

4. Clear Codes and Test Drive

After addressing the issues, clear the diagnostic codes using the OBD-II scanner.
Reconnect the negative battery terminal.
Start the vehicle and ensure the check engine light is off.
Perform a test drive to ensure the vehicle operates normally and that the check engine light does not reappear.
