Assuming I wrote the code correctly, it is showing Evaporator Vent control error per my machanic.
Attemting to reshearch the most likly casues. I have already replaced the gas cap. I always "click" the cap, and since I have 2 cars at 200K, I think I can say that's not it. Since seems like it will be one of those best guess things. No "apparent" leaks or cracks in the hoses or vent lines.

Any suggestions. Since my Avalon has been recalled, I can wait till it gets taken in and them look at it I suppose.
