I agree with all the posts here, just be prepared for the standard "lets reset the code and see if it comes back" response. Frustrating because usually they won't even look at it unless this code is a known issue.
On my 98 honda, I had a couple CELs (check engine lights) and the standard response was to "tighten the gas cap" and see if it would go away on its own. Never worked.
Do some research on the code, and be prepared to push the dealer into fixing the issue, especially since you are close to warranty end. Hopefully you won't have to push, and they will do the right thing.
