Make sure your fuel cap is tight and that it is the right one for the car. after that just check every thing and make sure there is no leaks in your fuel lines anywhere.

well i kno for a fact the little flap that covers the hole for my fuel tank is missing...could that be a possible cause?

Possibly... Id try another gas cap first.Maybe borrow a friends. Dont forget to tighten the gas cap until it clicks.

The way this code gets thrown is like this. The car will put the gas tank into a vacuume and whach it to see if it bleeds off. If it does then the computure will throw a code and turn your check engine light on.

you have to remember its a honda, CEL can happen from switching small things
