found this, but not sure if it applies to the 02. since you just did a swap, i would double check all the wire connectors. open, clean and re-seat them all.

P0447 evaporated emissions system vent control circuit open.
this an open circuit, a wiring issue most likely. i have read stories about salt corroding the wires at the connector on the charcoal canister on the rear of the car behind the RR tire. i'm not sure if this applies to your year. check all the connectors you have messed with, again.

this is often caused by the front o2 sensor being tired . and is usually corrected by a subaru or VERY HIGH QUALITY replacement o2 sensor. some low price o2 units will not correct the issue.

there are also other things that will cause this, especially exhaust leaks.
