Check engine light causes?

[2013 Geee T]

While driving home today on the freeway in 30 degree weather with freezing rain my check engine light decided to come on.

Are there some common causes for that? Weather related?

Will disconnecting the battery possibly help?

Can Autozone check a code on a check engine light?

Will there be a 4th question?

Yes, Autozone can pull the code for you for free.

Its an engine coolant temperature sensor issue. It says it was operating too cold. I forgot to get the code number like in idiot though.

Where is the temperature sensor located at?

I disconnected the battery and now the service engine light went off so Im going to assume it didnt like the cold conditions.

Disconnecting the battery just resets the computer.

If there is a problem with the sensor...it will come back.

I really think it was because it was super cold out driving 70 on the freeway. The car didnt want to warm up the whole way home. The temp gauge is fine now and goes to normal. If it comes back Ill worry about it then but for now I keep my fingers crossed.

weather has nothing to do with a check engine light coming on or not. if it comes on again get it checked out.

If the coolant temperature does not go up to normal for a while the light will come on... this normally happens if the thermostat is not closing tightly and let some cooland pass through the radiator... this thermostat failure is more evident on extreme cold weather...

I changed mine one month ago as it was taking too long to reach normal temp... Now it goes up in a few minutes...
