In fact, if you can find a way to isolate the knock sensor, then you could see if it was something like the harmonic balancer creating shock waves. I had a stuck in base boost that was a noisy balancer throwing impact to the block, the knock sensor read it as a faux cylinder knock.
Get a stethescope and listen to the engine, see if you can hear any odd sounds that are telling the sensor to go to base.
Pedal switches for the cruise control come to mind as well. Does your cruise control work?
