If your gas tank cap is not sealing because it is missing the seal or because you have not tightened it until it clicks, you can get a similar code since unexpected air will be introduced the system.
My gas cap looks ok and it seals pretty good...

although the crankcase vent recirculation hose is probably the cause i cleaned it last time and took 3 weeks before the codes came back... i might have put a hole on it or gotten it worse when i was cleaning.. I noticed that when its really hot outside 95 degrees + the error seems to come back and everytime i checked the crankcase vent seems loose. ill check again tonight.

I will let you know thanks on the heads up...
