It sounds like the PCM might be bad, but we should check the wiring to injector #1 as well because this is what the codes are saying.
P0201 - This code signifies that there is a problem with the fuel injector circuit in cylinder 1.
P0206 - This code indicates a problem with the fuel injector circuit in cylinder 6.
You may have shorted fuel injectors which we can test by going over this guide:

Shorted wiring at the injectors or shorted injectors can cause the other codes as well but if the injectors test good and the wiring is okay, I would remove the PCM and send it in for testing/rebuilding here is the location of the PCM so you can check it out.
