To your issue get a new gas cap, did you get one from your previous thread?

 

February of this yr. some people suggested i try to replace the canister purdge selinoid.

Same advice applies as it did back then. Usually the caps don't fail, in my experience. Two 2009 CR-Vs, same error in both. Unless you don't mind doing the work yourself, you'll need a mechanic or a Honda service department to do the diagnostic and replace the part.

 

I had this problem on occasion with my 2008 CRV.

The alert is of course telling the dirver there is an evap leak in the fuel system and most often this is a loose fuel cap.. hence Honda makes that the alert focus.. as it is the easiest and most common cause (cap not fully tightened, or missing).

In my 2008 with this, and it was the fuel cap. Cap was not bad, it's just that it had something about it that it would feel closed, when in fact there was a half a turn left to get a full seal. So.. I learned to just make sure I pushed past that first hesitation point when putting the cap back on after fueling. Eventually, I bought a new cap and never had any sticking spot like I did in the old cap.

 

This is an evap emission system fault.
After checking the fuel cap and its seal, the next steps require knowledge of how the system works and how vehicle goes about testing the system integrity. A smoke machine becomes very useful in such cases. The machine is usually attached in the engine bay where the purge valve connects to the system. And will show if there is a leak and how fast it is. The smoke that is fed into the system will find it way to the leak. That is hopefully it will show where it is coming from. It may be hard to find because of all the hoses and where it goes, hidden sometimes. The DIYer has to have a good skill set to find the small evap leak.
Good luck.

 

I got this once, couple years ago. Clean cap gasket, replace cap. If that don't solve it, address the canister thingamajig.
Mine issue has never been back.

 

It is most likely the canister purdge selinoid. My 2010 had the same thing, and eventually the check engine light will come on. Drove it that way for 4 years before I really got tired of seeing it. Bought the part on Amazon, really only took about 20 minutes total to replace, and I am not that mechanicaly inclined. Just a bit of a pain to reach.
