P0102, P0113, P0A0D after cleaning EGR, InManifold, and hybrid batt cooloing fan

So my 2011 Prius with 240k started having rough running at mid rpms, going up slight hills. It was fine with throttle open all the way or closed, idled great, but mid rpms it would run rough. So I watch YT videos and started cleaning the EGR pipe as described. When I reassembled it started, but ran even rougher. Shut it off and decided to go through the whole cooler cleaning and manifold cleaning process. When I put it back together it displayed Check Hybrid System and would not start. I did forget to reinsert the mass airflow sensor plug. So I plugged that back in and disconnected battery then tried again, but same codes come up after that. Still wont start. Any ideas? I am thinking I need to take it to dealer and have them diagnose it. I see one of my cells is low, but what are the chances that that is the problem?

When I cleaned the manifold, I removed the sensor that has wires going to it. I did not clean that part at all, i just put it back as I found it. I cleaned the manifold with carb cleaner and purple power. I used brake cleaner and power washed the cooler, and carb cleaner on the valve portion of the EGR. I don't know the 12 volt health, how would I find that out? I also did not examine the plug to look for corrosion. I will do that now. Thanks for your help. I think I'm in over my head.

 

I did clean the throttle body with carb cleaner. I did not touch the hybrid plug until today and I simply unplugged it and put it back in as a last resort. I forgot to mention that I also changed the spark plugs if that matters.
