P0327/P0332 Help This has been going on for several months now...
I've read all the info I can find...
http://www.hotrodlane.cc/New%20LS%20...or%20P0332.htm
Replaced front sensor and wire harness... no relief. What else can trip this code aside from the harness/sensors? Will real knock cause the codes?
PCM?
MAF?
MAP sensor?
Anything like that potentially an issue?

Sensors from GMPartsDirect, harness I went to Pace Performance.
joecar, I did what I could without having a scan tool. I do have a friend at a performance shop who said he could datacapture on his laptop and go from there. I'll try to get that done in the next couple days.
I was also told if could be a fuel pressure issue? This is a headache I didn't need right now.
It's throwing both codes at once... and the harness I removed and the harness I put in have both checked out ok (60 bucks down the tube there).

If the subharness is good, and if the sensors are good, then that leaves the vehicle harness, the PCM connectors, the PCM, and possibly some ground connections.

A little necro but this problem is still ongoing. 
Took the car apart again and discovered the rear knock sensor was broken..

P0332 code is gone but P0327 is still on. What are the chances I got a bad knock sensor from GM Parts Direct??

Matt, fuses are all good. Pulled the front sensor and replaced again. Code stayed off for about 3 hours (a dozen drive cycles going WOT and normal driving.). As I was leaving work the damn code came back. I hear a little noise from the engine bay. Pulled valvecovers and checked every pushrods/rocker for problems and found nothing. I suspect the waterpump or a pulley is making the noise. Any chance of either of those tossing this code? I'm going out of my mind... Granted I'm able to do the workl myself but 150 in parts and hours wasted and I'm still fighting this.
