Hello, I've been having in issue with my recently purchased 2012 Honda Accord SE. For the past couple of months I've been getting the "Check Fuel Cap" message, I tried changing the fuel cap with a OEM cap and I still get the message. I took it to pepboys where they suggested a smoke test. They found no leaks and suggested I take it to the Honda dealership because it might be a "system glitch" any idea on what this might mean? Also, I should mention that my check engine light NEVER came on.

 

After every fuel fill-up. just tightened the fuel cap at least 3 clicks. If you tighten it at least 3 clicks, you should not have the issue anymore; unless the gasket was bad.

The 3-clicks (at least) is part of published Honda info. to techs/advisers.

 

I thought it was pretty obvious but yes I do tighten the fuel cap enough. I even changed the gas cap itself.

 

Do you turn it til you hear at least 3 clicks? That part is not an obvious procedure for most Honda owners.

 

The system must be detecting a large evap leak,for it to think the gas cap is loose.

This is not a solution you will find on the internet,your best bet is to Google or Yelp a competent repair shop in your area

(Pepboys is the Walmart of the repair industry. It is a running joke and should be avoided.....)
