I'm hoping this is related to the transmission fluid job I did yesterday, and just knocked something loose. I did a cursory check this morning of the diverter valves and the plumbing running to them, and it all seems to check out.

I cleared the codes, and they come back instantly, no delay. I will probably just have to live with the code for a few weeks since i head back to my regular flying out Mon returning Fri job next week, and my car lives at the airport. That and it is too freaking cold... Have a year before I need to get my emissions done, so I have some time.

Well P0410 has to do with the your secondary air pump. Either the pump is faulty or the fuse/diverter have issues.
Not too sure why this will have to do with you doing a transmission flush since this part is not close to the transmission. All i can say it is not a big issue. Sometimes it could be related to cold weather. For some reasons you have water in your pump freezing while parked at night and preventing it to run in the morning when you start the car

The reason I say it has to do with my flush, is that when I was trying to get the breaker bar/36mm socket to the crankshaft pulley to rotate the torque converter to get to the TC drain plug, I might have pinched one of the vacuum lines. I did remove the air intake ducting from the bumper to the filters, and the engine cover, part of the vacuum lines that lead to the diverter are attached to it, which I unclipped. The timing is suspect, that is all. It is most likely just pure coincidence.

I have already been looking into the steps needed to access the SAI, which involved removing the bumper...

Yes the pump is right behind the bumper driver's side where the temperature sensor is. I hope you'll find/fix the issue.

Re-seated all the plumbing, cleared the code, all is well in the world.

Good work.

And the world came crumbling down lol

What I have done so far.

Checked air pump - functional
Replaced both downstream O2 sensors.
Removed and cleaned (or replaced 2 cracked) hard pressure lines
Cleaned MAF sensors

I'm about to pull the diverter valves and clean them out...
