CEL code 0446

About a month ago, I cleaned my MAF and throttle body on my '04 Tacoma 3.4L. A week later my CEL came on (assuming it was the MAF ruined) and after getting the reading, it was 0446 with 0441 pending. I changed the gas cap with a Toyota one, but the light is back on. I also tested the 3 VSVs and all 3 seem to work, though the one by the charcoal canister isnt as loud. I guess I have two questions:
1) Did cleaning the MAF and throttle body cause this indirectly?
2) Should I try to replace the VSV for pressure switching first since its the cheaper part, then if that doesnt work, change the canister?

Thanks!
