After several weeks of getting the "Check Fuel Cap" message, I finally installed a new NAPA after market fuel cap. Still kept getting the same message. So finally took it to the Dealer who tried to tell me the problem was I didn't come there first to get a "$100" Honda fuel cap!! (Tongue in cheek.) Never really resolved the issue; I just try to give the cap a couple of extra turns each time I refuel. My suspicion is that whatever "senses" the fuel vapor pressure in the tank is sending false readings to the computer. But what do I know.
