could an overheat problem or temp sending unit cause a light to come on??
I thought not but could be wrong.
anything is possible. on what type of vehicle? gm’s do it all the time for not reaching operating temperature. Fords usually for running too hot.

my old outback threw a CEL when it overheated, so it’s definitely possible.
just go to an advance auto and get a free CEL test
