Default Re: Eng. Fault code PO446 Evap. System need Help.

I have one thing to add. I live in Michigan and its very "moist" here. the same code had appeared on mine 3 times in 5 years. I just cleared it and it stayed gone for a long time. it seemed to set if we had a huge change in temp or humidity. being as the tech guy is in AZ. and the Problem is NY. I believe that is lost in translation. I tend to wonder if the NY guy is fighting the moisture issue I was having. seemed to set if I had less then 1/2 tank when the temp changed.
