It means that the car has detected a malfunction. The car can tell you a code than indicates what the malfunction is, if you have a code reading device, along with a book or software that tells what the code means. However, most people know that this light means to take the car to your mechanic.

Check engine lights are an indication that there could be a problem with the engine, ignition, or fuel line system. This could also be a bad sensor.
