Both those codes are evaporative emmisions codes. O2 sensors don't have anything to do with it. Check your gas cap first. If its loose, there ya go. If the seal is dried out and not sealing properly that can do it too. Otherwise it could be a vsv thats died or a disconnected hose or tear in one of the hoses in that system.

When did you do it? The monitors for the evap test take a while to complete. You'd either need to clear the codes and see if it comes back on, or wait a real long time. The ECM will turn off the light if it passes "x" amount of times in a row. I don't remember what that magic number is, but it would take weeks if not months to do.

i am having issues with p0446 as well!! what a pain!
i've gone to two shops to fix this issue so far. i just went to the second one today. the first one had no idea what they were doing and just started replacing parts hoping to fix the problem... biggest bunch of idiots ever. hopefully this second shop fixes it. they found two cracked vacuum lines today and replaced them..
