Having a PO327 code issue

[sprayed99]

I have replaced both the knock sensors and harness with brand new GM parts and did the silicone treatment per the GM TSB. I still get the PO327 code. The original 5.3l that had 99K on it never had this issue, but when I dropped in the known good 6.0L I started having this issue. I will attach a few files later tonight for youe viewing pleasure .

I have a guy helping me do the VE tuning so the tune file will be a SD file.

Can any of the knock sensor tables cause this code?

Odd no responses.


How do I attach a file here?

Can anything in this tune file be causing my PO327 or PO332???

Your tune won't cause the code.

Here's how it works:
The PCM looks at the voltage across the knock sensors at key on. If the voltage is incorrect you get a code.

So, either you have a bad sensor, bad connection, or you insulated the bottom of the knock sensor which provides the ground connection for the knock circuit.
