fuel cap light on 2007 Honda Ridgeline

I keep getting the 'tighten fuel cap' message in the scrolling display even though I use the three click rule. The check engine light is not on. The dealer that i go to says that if you don't tighten it correctly this message will display for the next four of five times you start the truck. I've been getting the message for over a month now. What does this mean?

Check your gas cap for damage to the seal ie. cracks, nicks, in the rubber seal. If all that looks ok take your car to a local parts store and have them reset the codes for you. Once a code is set in a OBD II system it has to be reset with a scan tool. Your local auto parts store will do this free. If the light comes back on after that, have a shop that has a smoke machine diag. for leak in vaccum lines, cap and hoses to gas tank and vapor return.
