Sub-step 1: Use the OBD-II scanner to read and document the error codes.
Sub-step 2: Research the error codes to determine the underlying issues, such as faulty sensors, misfires, or emission control failures.

3. Repair Faulty Components

Sub-step 1: If the error code indicates a specific sensor (e.g., O2 sensor, MAF sensor), locate the sensor and disconnect its electrical connector.
Sub-step 2: Remove the faulty sensor using the appropriate socket or wrench.
Sub-step 3: Install the new sensor, ensuring it is securely fastened and reattach the electrical connector.
Sub-step 4: If necessary, replace any damaged hoses or wiring identified during the inspection.

4. Clear Error Codes

Sub-step 1: Reconnect the battery negative terminal.
Sub-step 2: Use the OBD-II scanner to clear the error codes from the vehicle’s computer.

5. Test Drive

Sub-step 1: Start the engine and allow it to reach operating temperature.
Sub-step 2: Take the vehicle for a test drive to ensure the check engine light remains off and the engine operates smoothly.
