What you can do is make sure the gas cap is tightened properly for more than 3 clicks, and drive the car for 3 days or so under normal driving conditions. The light will go out if there is no problem in the evaporative system; Otherwise, it will remain on, and you need to have the car check out by your Honda dealer. Don't take it to any repair shop because the inspection required to diagnose the cause of the problem must be done by someone who knows how the system works.
