Yeah, they're nice. I got the same and pulled a code from my 02 sube, researched online, determined that it wasn't that important and reset the check engine light and have been fine.
I have an "Ultra-Gauge" attached to my Tacoma. Contained within the wealth of knowledge given my by that little bugger is a code reader and a code clearer. If a code cannot be cleared then off I go to a search engine for the Oracle of Truth or I go to the thread "How T Fix Stuff" to find what the code means and how to fix it.
