Have any of you guys had a knock sensor go bad. I keep getting a P0332 code. It is for a knock sensor voltage low. The test basically calls for replacement. I just wanted to know if any of you guys have had these problems at all.

 

I think that's the code i got when i forgot to plug the knock sensor harness back in after my intake swap. But a lot of people get it after intake manifold swaps when the pinch the wire under the intake causing it to ground out on the valley cover.

 

yeah, there is actually a TSB on the knock sensors for them getting corrided cuz water gets to them so how. i got mine replaced. the rubber on the old ones where hard as a rock

 

well i thought it was gone but it came back lastnight while driving home...po332....now i dont have alot of experience with these engine controllers but i was scanning it while driving home(the nice advantage of working at a dealer...i get to bring the scantool home with me so i can monitor) and it was up arount 34 deg. of timing in wot when the ses light was on. Tonight it felt real flat and like it was down on power; like timing was pulled due to knock sensor problems. Any suggestions

 

Just put a sensor in it. I have replaced both of mine, for p0332 and p0337. p0332 should be the front one, if I remember right. It will cost you about $100 in parts for the two of them. I'de replace both cause if one went bad the other usually isn't far behind.
