2008 Honda Civic LX - Check Engine Light?

I drove my car this morning to work and it was fine. I even gave it a nice 10-15 mins warm up before driving because winter in Wisconsin is terrible. When I finished my shift, I started my car and the check engine light came on. I'm not sure what I should do. I'm thinking of the cold weather, but I'm open to anyone who know cars well. Just need to get this issue over with. I'm hoping it's not a big issue.

A check engine light means a problems has occurred. So take it to your mechanic or Honda dlr and get the code checked and problem fixed before a small problem becomes a big expensive one…

As has been explained here several thousand times before, no one can diagnose these things over a forum. Ever. Get thee to some place that can pull the codes and read them.
