You "had" the wiring "swapped out"... I wish you could see how I'm clutching my forehead right now.
DO NOT replace wires wholesale on a whim.
DO find the exact thing to repair before taking any further action.
You could have easily tested the entire PNP circuit with a DVOM from the comfort of the passenger seat at the PCM without introducing unknown elements and without incurring further financial penalties... There likely was a single issue, now... now it's not as simple.
On a side note: Being told something is adjusted is not confirmation that something is adjusted. Even in a professional setting, if you bring me a car with a PNP DTC and tell me "it's been adjusted", you can be sure that I'll check the adjustment even faster and harder than if you tell me it's never been touched. I've seen what people do trying to fix cars and let me tell you, it's nasty.

It's just that I'm at such a point of desperation with the car I can't help but see that "brute forcing" my way to a solution is the only way I can fix this hence the swapping out of parts. You said I can test the pnp circuit with a dvom from the pcm, is there a handbook or some documentation that coukd show how I can go about doing this since I have a multimeter.
Also after seeing the swapping of the wiring didn't work I swapped back to my original wires and thats when the other codes came up.
