Check engine light comes on for no reason why?

Hi Jonna.
not sure if this will help you out,but its what i have found on the internet.

Your car's "Check Engine" or "Service Engine Soon" light can flash on for more than 1,400 different reasons, and in the coming months, we're going to share with you what some of those reasons are. The light is part of your vehicle's on-board diagnostics (OBD) system and can indicate anything from a quick fix like a loose gas cap to a major repair like a catalytic converter.
Trouble code: P0217 Engine Over Temperature
If this code is discovered, it means the engine coolant temperature is excessively high under normal engine speed. The engine coolant is overheating if it's around 240 to 250 degrees. This is a critical light! It means your engine is beginning to overheat.
In addition to the check engine light, you might also see some other type of warning on the dashboard, such as a red temperature gauge or maybe the words "engine hot."
The warning lights should come on before any damage to your engine occurs, but you need to shut the engine off as soon as possible.
