Angry 2011 Versa 1.8L PCM/ECM/ECU Issues?

Greetings.

I'm new here & new to the world of Versas.

2011 Versa S 1.8L auto(non-cvt) 5 door hatchback.

Having some very strange issues.
I think the alternator may have been charging way too high (15V).
The bearings were squaking, so I replaced it with one from a bone yard.

Verified 14V after first starting.

However, now it has trouble starting & driving.
Threw codes for the Accelerator Pedal Position sensor so I replaced that with one from a junkyard.

The codes have not gone away, no matter how many times I clear them with my scan tool.
Sensor D shows a % when applying the pedal, but sensor E shows nothing.

I'm not sure if the new-to-me APP is bad or if there is an issue from the alternator.
Randomly, I'll get a code for the crank sensor or other things and the power is way down.

When driving, the cruise will not set, the rev limiter hits at 2600RPM in 1st gear & at ~4500RPM in 2nd.
When touching the brake pedal & accelerator pedal, the engine will "die" to idle.
When driving slowly & pressing the accelerator to the floor, it will not downshift & gains speed very slowly.

So. Does it have a PCM or ECM or ECU?
How can I check the PCM/ECM/ECU to see if it is working correctly?
How can I check the APP to see if it's working correctly?

TIA
