2007 Tahoe random codes

[JChis]

I have a 2007 LTZ Tahoe. It is going into reduced power mode and getting a service stabillitrack warning. I pulled the codes and it seems there is alot of random codes.

P0341 camshaft position sensor
P0481 fan 2 control circuit
P0641 sensor reference voltage
P01682 ignition 1 switch circuit 2
P0335 crank sensor

I can clear these codes and drive the vehicle down the road, it runs fine for a few minutes and then goes back to reduced power mode and the codes come back. I replaced the cam sensor and the crank sensor, still the same thing. Any suggestions?

Is there any update to this error?
I'm getting exactly same issues.
I already changed a brand new fuel pump (which included fuel pressure sensor).
Looking to replace crankshaft position sensor today.
Also will check Throttle body harness/terminal. (Which I replaced with a brand new OEM one last year).
This is really annoying and I have to clear the codes in order to drive it.
I took it to the shop and they have no idea. :whymewhyme:
