Light came on and I took to local auto parts store that does free code check. Came back camshaft position sensor back 2 bad. So I replaced both, Light stayed on. So I bought a scan tool. https://www.boschdiagnostics.com/diy/products/bosch-obd-1200 and went home to do some testing. First time around I came up with:

I pulled plugs and tested AC voltage on both new sensors, and they were working fine. After some searching, I found a possible cause would be VVT stuck, or the Phaser is going out. I pulled everything on bank to side and removed valve cover, and phaser isn't bent or stuck, so I put it all back together (unplugged battery for this) and after 4 engine run cycles I came up with these codes.

I still have same last 11 codes (5 OBD2 and 6 PCM)
Fuse 32 isn't blown. I do have 12.4 volts on pin #1 for the VVT actuator connector.
I'm spent, confused and running out of money/time. I have to be in for vehicle inspection by 1/15/2020, and they do pug into the OBD port and check.
Please help. Willing to accept PCM as probable cause, as much as it will hurt.
