Code po332
 

My truck has a po332 code which is for a knock sensor. My knock sensors are new and My motor has never gotten wet so I know that's not the problem. I do notice my truck makes a lot of lifter noise. Could that be causing a false reading? My truck also seems to be sluggish. Would this cause a low power problem? My truck just has a base tune in it and I'm bringing it to be tuned in the next couple of weeks. I want to get these bugs worked out before it hits the dyno

False? We don't know its false yet, you might actually have knock....

How bad is the lifter noise, and did you do heads/cam or something like that? If you have noisy lifters (beyond the normal "ls motors are noisy" level), then you probably have a mechanical problem. Ruling out a cause of knock while an actual defect exists won't get us anywhere.

I just went though thiz on my suburban . I replace my knock sensors when I did my intake gaskets using bwd sensors from Advance Auto Parts a new harness from Dorman. About 3,000 miles I have my check engine light come on for the p0332 knock sensor too low signal + short. I had to put my intake back off and I replace the knock sensors with the OEM Delphi and new harness harness. So far it has not come back I found out that the aftermarket knock sensors not that great

Brew city it does have a cam. Truck dude, those are the same knock sensors I used. Where do you buy the Delphi sensors...Dealer only?

No i ordered them from advance auto made them warranty them out it took them about a week to get them they where actlay cheaper then the bwds i bought the dephi number is AS10017 i paid 46 for them where are the advance brand was 56 each, i made them warranty the knocks sensors the harness and intake gaskets when i redid mine. but i also have a comerical account so they wanted to keep me happy, but it would not be unreasonable for a walk in customer to ask for all that to be warrantied out

You may need to adjust the Knock threshold in the tune do to the cam and headers...

That's something my tuner can do correct?
