Guys/Gals
I need help. I have a 2000 RX that was throwing codes 440, 441 and 446. I just replaced the canister and it is still throwing codes 440 and 446. What else could it be? I checked the connection at the air box and that was OK. During the winter it does not throw codes only once it warms up outside. Could it be the gas cap? I already replaced it but on the cap is says vacuum only. Is there different caps? This thing is driving me nuts and I am tired of spending big bucks trying to fix it. Any suggestions?

Trying a new Lexus (Toyota) gas cap would probably be the cheapest thing to try.
-You should hear a sucking sound when you open the gas cap.
