P3190 Code & Death After Oil Change

I see what you mean. Yes, bad technique when removing the Gen 2 filter could allow debris to drop into the right side chamber and cause problems. Thanks for the clarification.

OK, I know there are a lot of threads regarding P3190. At the risk of overlapping similar previous posts, here's my story:

I took my wife's 2008 Prius (~150,000 mi) in for an oil change. It's had no reliability issues since I replaced the brake actuator 2 years ago. The oil change guys (independent shop, but "quick-lube" vibes) did nothing more, as far as I know, than drain the oil, replace the filter, and open the air cleaner housing to check the air filter. They removed the filter to show me some tree debris that it had caught, but knowing it's a young filter I told them not to worry about it and put the filter back in.

Upon leaving the lube place, after literally 1/2 block I notice I'm on battery with the triangle of death, VSC and ABS lights illuminated. I made it to the next light and pulled into a side street before the car came to a stop. I checked the oil level (fine), connection to the oil pressure sender, and all other visible connections. that could have been disturbed, but found no issues. After a few Hail Mary attempts to restart I had it towed home. (Thanks, USAA!)

One factor I considered is that critters have been under the hood and left acorn shells and droppings around the air cleaner cover, so possibly something dropped in when the oil guy opened it up. Indeed I found one rat/mouse turd on the butterfly valve and fished that out. But I did not find any issues with the MFC.

So, I know correlation is not necessarily causation, but it seems likely something happened during the oil change. I've checked and double checked all the connections I can see, and found nothing amiss. I plan to take off the MFC tomorrow and clean it as described in other threads, but am not hopeful. I don't want to make recovery more difficult by running the traction battery even lower with restart attempts.

So I throw myself at the mercy of the court: what else should I look for or do before I tow it to the dealer?

Look for a dealer you don't like clear the codes and trade it in under busiest day. As long as there's no money indicated lite on the dash they probably won't even check it. Screw them the way they screw us
