First thing is to get the OBD-II codes read, see what is causing the CEL to come on.

#1668 of 1691 got a code reader? by Stever@Edmunds HOST

A reporter is looking to hear from consumers who own a "code reader" - either an app or an appliance that allows the user to tap into his/her car's diagnostic system to understand why the Check Engine light etc is on, and perhaps shut it off. If you have used one of these apps or systems and are willing to share your story with a reporter, please email PR

edmunds.com no later than Monday, March 5, 2012 with your daytime contact information.

Check engine light and gas cap. I have repeatedly had the problem. After an expensive diagnostic test I bought the recommended new gas cap. The problem continued! My discovery is that the filler spout to the gas tank is out of round and will not seal properly. To determine if yours is not round it should be checked with a dial indicator as it is not detectable by the naked eye. I have contacted American Honda and have a case #, but they need more evidence to determine if this should constitute a recall item.
