Any code(s) or just a light? Other symptoms...what car, etc.

A CEL means the ECU is detecting a fault with the emissions control systems of the car. It turns on the light to let you know it needs to be fixed because the problem is increasing the harmful emissions output of the engine.
Knowing the important info above will help determine how to retrieve the fault codes which will in turn determine the necessary repairs.

swing by a PepBoys or other such place, they will read the code at no charge. Have them clear the ECU if they will and report the code(s) here. Monitor how quickly the light comes back on and be prepared to have the system read again but, it seems it will set the code repeatedly.
