P0327 Knock Sensor Low Voltage
I just got a P0327 knock sensor code thrown on my way home today. I washed the motor a couple days ago and just got back from offroading and bouncing around a little bit, code came on as soon as I tried to smoke the tires after I got back on the road. I have never taken the manifold off. How likely is it that the knock sensors got wet? Any other causes?

i washed my engine and I had the p0332 come up. My sensor was rusted like hell. I would expect your sensor has gotten wet if you washed your engine, and probably is on its way out.

The thing that is interesting is that if I clear the code it won't come back until I wail on the motor some. After clearing the code once last night I went out and did a nice burnout on the street, then drove to the store without the light coming on. On the way home I did a WOT run from 0-90 or so, and as soon as I was done with it the code came back. I was monitoring the WOT run too and I was maxed at 8* KR the entire run.
