There's something wrong with your catalytic converter. I've heard that they have a warranty on them. Have a local honda dealership check it out, tell them your converter is setting the check engine light off. It's not normal but it's a common problem.

Don't quote me on this but I thought the warranty on a converter was 7 years or 80,000 miles.
