The check engine light (also known as the malfunction indicator lamp or MIL) serves as a dashboard warning signal that a vehicle’s onboard diagnostics system (OBD-II) has detected a malfunction affecting the engine, emissions, or transmission.
When illuminated, the system stores a diagnostic trouble code (DTC) to help identify the specific issue, which can range from a loose gas cap to serious problems like misfiring spark plugs or a failing catalytic converter.
Steady Light: Indicates a minor or non-urgent fault (e.g., loose gas cap, sensor issue); the vehicle is generally safe to drive but should be serviced soon.
Flashing Light: Indicates a severe fault (e.g., active engine misfire) that can cause immediate damage to the catalytic converter or engine; this requires immediate attention and often means you should stop driving.
