Another P0327 question
Another P0327 question I replaced the valley cover on my 1998 Z28 LS1 with the LS6 cover and replaced the knock sensors at the same time and also the wiring harness. The knock sensors are AC Delco. I bought 2 torque wrenches so that I could get all the torque specs correct. I think the 3rd day of driving I started getting a P0327 code (cel on) I cleared it. Can a tuner adjust the sensitivity and make this go away or did I just get a bad knock sensor? When I installed the intake I made sure to tape down the wiring harness so it would not get trapped one of the bumps on the valley cover and the intake.
OK how about if I give a little more detail.
it's a 1998 Z28 LS1 I had the entire top end rebuilt to a 2004 Z06 engine with genuine GM parts. The guy that built my motor sent it to a Tuner and the tuner turned off the knock sensors. I replaced all of the parts listed above.
Now the service engine light comes on and then after a couple of restarts it goes out and then after a while it comes back on and then it goes out. It keeps resetting itself.
I checked the knock sensors for resistance with the info I got from Gear Chatter and I also checked them with an AC volt meter and tapped on the block like it said in the Gear Chatter instruction. All seems to be well with the knock sensors. I've read in places that a Tuner can adjust the sensors is this true or fiction? I bought the car in 1997 and drove it without issue until I rebuilt the engine. Does the extra 100 HP added when built make more noise and should the knock sensor settings be adjusted to the 405 HP LS6 settings?

Just turn the code off in the DTC list. That doesn't keep the knock sensor from working. Having the code set does make the PCM pull the Max KR allowed in PE table when you enter PE.
I'm think maybe I should just spend the $800 and purchase the tuning software and learn how to do this myself, I just hate spending that kind of money to fix just one car. Thanx for your reply.
I'm having an issue with my 1998 Z28. It started life as an LS1 but then I replaced everything except the crankshaft and pistons with GMPP parts for a 2004 Z06 motor and it runs Great except.........
I had someone tune this and he turned off the knock sensors because he said they were bad.
I replaced the knock sensors and wire harness with AC Delco parts and had another Tuner turn them back on. (99+ sensors and harness)
I'm getting code P0327 only no other codes. I read the GearChatter post on how to test them and I think my results are Good.
Checking at disconnected harness I'm getting 100 KO on each sensor and then I did the AC volt on the meter and knock on the block test and both sensors read the same.
I disconnected the Blue connector from the PCM checked there and got the same results. 100 KO
I removed the PCM and checked between the pins (68 & 69) and the body of the PCM and got 4.83 & 4.84 KO
I'm thinking it's in the tune, am I correct? I get the same reading off each sensor and only 1 throws a code.
