Check engine light came on this morning on the way to work.

If no other issue are apparent (it runs good) then wait a few days before taking it in. If the problem is minor and intermittent the light may go out, meaning the engine computer has run and passed its emissions "monitors". There are many reasons the check engine light can be turned on, and the only way to know is to have someone scan it for codes and the code itself won't tell you what is wrong. Don't ignore the light but don't freakout either. If it stays on then take it in and get it checked.
