Dig through here and you'll find it... I love my Helms but it would be nice if it had a badass index, haha.

I just spent like 20 minutes looking through my Helms.
It doesn't say much. There's an entire page (11-77) devoted to the knock sensor troubleshooting, but it doesn't tell you voltage. Let me know and I can type that page out for you.
The other page (11-37) describing the ECM pins shows that the knock sensor should read a pulsing signal on a multimeter (while the engine is running). It's strange because for every other sensor, it tells you the voltage. I'm gonna make a guess based on the other sensor readings that it should pulse between 0V and 5V.
