When a problem exists in your engine bay usually a sensor will energize or deenergize, opening or closing a circuit, and will be recognized by your ECU. Once your ECU sees this it will send voltage to your dashes check engine light. Upon completing this circuit the engine indicator is will illuminate, signaling to the driver of a fault existing.
Please send more info about what's going on with your engine. Anything! The last time you tuned it up... If it sputters... Personal modifications... Anything.
