P2195 Code, bank 1 sensor 1 stuck lean

I am working on a 2012 Prius V Five with 177K miles. I just bought the car recently as a fixer upper for the family. This is my second Prius, my other is a 2010 Prius Three. Back to the 2012 V, Originally the car would miss under the slightest acceleration. It took me a while to diagnose that issue because it produced no error codes. New plugs, swapped ignition coils, injectors, and egr assembly from a parts engine I have. Then I discovered a post about the intake. I found the intake manifold egr ports were clogged with carbon. All cleaned up and running smooth again. It was a relief to find the issue and fix it. Now I can finally drive it. First trip after the egr port cleaning the CEL is on P2195. I removed and cleaned o2 sensor, the light came back on. I then swapped both o2 sensors out of my 2010, my 2010 had zero issues. Again P2195. Ironically my 2010 now has the 2012 V o2 senors installed and it threw a P2196 stuck rich, just the opposite. Swapped back ALL the parts I changed the first time around, still the same result. I bought 2 new o2 sensors from Autozone, installed them P2195 is back. So what is next? Smoke tested, no intake leaks or exhaust manifold leaks. Installed a blind gasket for the egr to make sure it is not leaking, just threw another code along with the P2195. Any assistance or direction would be greatly appreciated.

 

I didn't have much time to do anything today. I did clear the codes and took it for a short run now P0032 is coming up. That is a heater circuit for sensor 1. I will check fuses and wiring in the next day or so.

 

Cleaned throttle body, cleaned MAF, swapped out MAF. I did not do anything to the MAP
