I just did a search, but I want to confirm what I found.

The only way to test a knock sensor is to put a meter on the ECU end of the harness, ignition on, and rap on the intake manifold, or near the senor and watch for voltage?

Correct, or not so much?

Damn...I was just searching the same thing...I also just ordered the knock sensor re-wire kit...thanks Shaeff(sp?)

page FI-34 in my TSRM say for voltage KS-E2 "crunking?" or running 2-4 STD voltage. I also found one other thing but i cant remember it off the top of my head but, I hope a pro sure chimes in here...thanks for this thread.
