Hello and welcome. My name is ***** ***** you for visiting the site, I am reviewing your question and will reply shortly, thanks.
Do you have the VIN handy?
I see, thanks.
There has been a factory service bulletin on some, (not a recall) for that type of concern. The VSV for the canister, causing both codes to set.
Here is what it states.
Under certain driving conditions, some 2000-2003 model year Avalon, Camry (NAP only) and Solara vehicles, and some 2001-2003 model year Sienna vehicles may exhibit a M.I.L. "ON" with DTC(s) P0440, P0441 and/or P0446 stored due to an inoperative Canister Closed Valve Vacuum Switching Valve (CCV VSV). The CCV assembly process has been changed to correct this condition.
