On my way to Las Vegas my check engine light came on. I kept driving because I was in the middle of nowhere and it was pouring rain. I have 58,000 miles on the car. The car runs perfect with no problems with the check engine light on. Is there any way to check the computer code without using a hand held code reader. Also could the check engine light come on because of some up coming maintenance that's due to the car. Forgive me if there any typo's, I'm using my side kick II to send this thread.
