" The gas cap is not installed or working properly
" The purge solenoid has failed
" The canister is plugged
p0441 has to deal with purge solenoid also.
P0446 has to do with the vent valve.
Sounds to me like the canister is plugged causing no venting or purging, if that is not the case I would check for voltage and ground at the vent solenoid and manually actuate them to see if they work
