I was looking over the trouble tree for the P0446 and you need a test light and a scan tool a professional one that can command the canister purge solenoid and vent solenoid on and off.

Like I said problem is you need a professional scan tool a diyer one can't command the canister purge solenoid or vent solenoid on and off. You could have a stuck vent solenoid plugged line somewhere.
