Check engine light codes, known as Diagnostic Trouble Codes (DTCs), are alphanumeric codes generated by a vehicle's onboard diagnostic system when it detects an issue. These codes can indicate a wide range of problems, from minor issues like a loose gas cap to more serious engine or emissions system failures. To read these codes, a mechanic or vehicle owner typically uses an OBD-II scanner. Understanding the specific code can help diagnose and address the underlying problem effectively.
