Bad news... It's not the sensor.
Had time to hook it up again tonight with a cold start (about 50°F again). When it started, it slowly and steadily built pressure up to about 40psi over the first two full seconds (no instant burst of pressure). It held steadily at ~40psi until the idle started to slow, then the pressure fell. It fell to 24psi. What's really bizarre is it fluctuated between 22-44psi for the entire warm-up cycle. I recorded about 5 minutes of the pressure test to give a better idea of what's happening (sorry! I did the one thing I can't stand, I held the phone upright...
). The video starts about 1-2 minutes after the cold start, but essentially you only missed the first 15 seconds, because after 15 it does the same thing until the video starts. Here's a YouTube link:

I guess it's comforting knowing it didn't fall below 22psi
I'm debating the scenarios in my head, wondering if it's worth it to fix it... I'd probably use OEM parts, and have it dealer serviced (because I have connections with employee discounts on both parts and labor). If this is the AFM pressure relief valve, how much will it cost to fix (or is this easy enough to do myself)? Looking for hours and part cost, I can calculate the rest. Or if it's the pressure regulator, what's the time and part cost there? I'm assuming it's a full oil pump replacement, and I'm assuming it's a LARGE number on the labor side. I definitely won't do this one myself...
Huge thanks again!
Ouch .
