Dodge charger p0300 and p0052
2012 Dodge Charger SE 3.6L V6
Hello, I have a P0052 and P0300 random misfire code. Originally I had all O2 sensor codes and a Camshaft sensor code. I changed the Camshaft sensor, all O2 sensors, spark plugs, coil packs, and my engine air filter. Now I only have P0052 bank 2 sensor 1 heater circuit high and p0300 random misfire. I swapped the O2 sensor with a known good one from sensor 2 bank 2. I have the Bosch O2 sensors which work up and downstream and I did not have to splice. My car battery was tested as well and I was told I would need a new one as the voltage was lower than the standard.
I'm at the point to where I have my PCM disconnected and I want to check resistance from my O2 sensor to the PCM. Can anyone link the wiring diagrams for the PCM and O2 sensors. I want to check everything I can with my PCM first. Also if anyone has had this issue before, please let me know what you did to solve the problem as I really need the help. I would bring it to a dodge dealer but the closest one is 20 miles away and I do not want to drive a misfiring car 20 miles there and back. I just changed all of my control arms and can't really afford to keep spending so much rn. The auto shop on my military base has horrible hours as well so I'm kinda stuck at home with limited tools. Thanks to anyone who can help!

sorry man I was rushing before work and I submitted the same post 3 times but it never sent so I had to re type thanks for letting me know though. I've been extremely stressed lately working this.
