Default Knock Sensor Low Voltage

I started getting code P0332 (KS low voltage) which is only one of the knock sensors. I plan on replacing both of them, but has anyone heard of these knock sensors going bad? I'm thinking that maybe I got water under the intake when I cleaned my engine. Since I only got a code for one of the knock sensors, it must be bad right? It seems if it were something else like the harness or pcm I'd get both KS codes (P0327 & P0332).

Yes, quite a few people have had one or both sensors go bad. Typically that SES is indicating a bad K-sensor, so you are correct.

Hey Tony! Long time no see. I hope all is well.

That's good to hear. I'm waiting on my LS1 Edit to arrive (I've been waiting three weeks as of today, so it should come any day) before I pull off my intake and replace the knock sensors; I plan on getting rid of my egr and A.I.R. systems at the same time. I want to delete those codes before I disconnect my battery and pull the intake. Anyway, thanks.

Jeff

There is a TSB for this problem. Something about water getting in from the rear area of the intake. Not sure if the TSB is F-Body or Y-Body.

Interesting Mello, that fits with the theory of getting water under the intake while cleaning the engine. Thanks.
