Getting a code scanning but no MIL light on the dash? Gliche with HPTUNNERS or Real?

[STR8BALLN]

I just happen to be logging and checked my DTC while scanning and I have P0327 Old,Current, Imature.

The weird thing is I have no MIL light or check engine light illuminated on the dash. I went and checked the DTC settings and it is not disabled and is set to report on second error. So I leave the p0327 in for a while and the the error is still there. But the odd thing is the DTC blinks in and out from no DTC reported to the P0327.

Do I really have a P0327 or is this a glich with HP Tuners?

Is this false or real? No timing is being pulled either.

You should check wiring ...or the sensor ..

Does the SES box have a check mark in it? If so it should set the light? Does the light work during the KOEO bulb check?

Ok, I just hated to replace anything with most guys reporting that at least they get a MIL light(check engine light).

Yes the box is checked, No KOEO bulb check done. I unplugged the MAF sensor and set it to first error and the MIL light came on just to do a check or test to see if the MIL light is working.

It just sucks, this new motor has about 2000 miles on it, and 2 brand new Knock sensors with harness and 1 sensor is already bad? My stockers had 150,000+ on them and still worked on the other engine.

Update:

I changed both Knock Senors a/c delco's and even got a new harness from GM. The car drove fine, then P0327 came back. When I had the intake off and inspected the valley, I found not moisture or oil inside the knock sensor wells. P0327 is back. Would a lean condition cause it to throw a code? Bad O2's? I noticed my O2's have not been switching like they should lately.

I don't know WTF it is now. Any takers or gurus?

"Immature" means it's faulted but not enough times in
a row to set the MIL (P0327 takes 2 key-cycles, each
seeing a fault, before setting the light).

Excessively lean could cause a lot of pinging but I don't
know whether pinging alone suffices to set a code. The
description indicates that a lack of activity is the fault
signature.

I am getting all of them Old,Current, Imature, History, Pending, etc.... Where should I look next?

Are you able to execute the diagnostic series that is
in the link, below the code details?

[SultanHassanMasTuning]

how are your knock sensors set up, if you have desensitized them too much it can cause this issue possibly

The settings are stock, I have not touched any knock sensor or burst knock tables.

I will this weekend.

Thanks
