Thanks callisto! I'll have to meter the pressure sensor if that seems to be what's in need of replacement.
I can do a continuity check on the wiring from the ecm as well.
I'm going to take one last look at the ecu. I recently pulled it to check the wiring, having found that same thread you linked. It sounded like the exact same issue, but I checked (so I thought anyways) the wiring was all intact. I'll give it one last check as there are potentially two connections I may have made (could be cpc and rear o2 potentially)

Here are some other good diagrams showing the whole system
