Low temp indicated

What would cause the low temp indicator code to show? What I mean is what temp sensor would determine that? And after the car warms up to normal temp should it go off or would the problem have to be fixed and code reset? And would that be why the engine idles faster as soon as the engine light comes on? Enough questions? haha. Thanks!

Re: Low temp indicated

An unplugged (or open circuited) coolant sensor throws a low temp code. About 3 seconds after you start the engine, does the check engine light come on?
