Thread: Knock sensors not reporting??

I haven't been able get any knock readout from my sensors the wiring is intact. is there anyway to disable them? I'm not asking to disable I need to know if it was possible that someone has removed the ability to report. it has a tune from the previous owner so idk what has all been done to it. Im in Nashville so if anyone has hp tuners or another way to check it out I'm all ears.
I ordered a 3.6 pulley and I will no install it until I can read knock
it has autolite 606's, open cone and a 2.5 dp, 175* thermo and don't ask how or why I have it, it was there when I got it.

are you sure it just doesn't have any kr?

Hit the block where the knock sensor is, or whack the crossover with a hammer and see if some KR shows up on the gauge.

when i scan it says no data received. i will try that, i'm surprised i didn't think of that...

What are you trying to read the kr with?

I can read every sensor on the car with decent accuracy but there is no data logged at all from the scanner. I've used every PID that can be used for my car. for some reason I doubt that I have 0 KR but being that I cant see that I'm afraid to add the 3.6, though I can't wait to

Have you ever measured KR or been able to ?

I figured it could be the scanner so in installed some plug-ins and still nothing.. with the strange tune, is it possible that the were told not to report and shouldn't I get a CEL for knocks if malfunctioning?

I got 0.0 on one PID once and since then no data has been received

as stated ^^ any sensor failure will almost always throw a CEL.... but I have never heard or seen of someone "disabling" knock sensors might wanna try an aeroforce/or equivalent... maybe the app/bluetooth combo isn't reading the data properly

I don't have the money for a 150.00 unit to scan. everything else is reading quickly, and reporting fine so why would this one sensor not read?

I don't mind waiting to put the new snout on but I have to do my coupler soon and if I have to take the snout off I might as well put the new snout with the 3.6, but only if I can scan for kr

Maybe its the configuration of the app. You have downloaded all the PIDS and plug-ins required. look around a bit on google there are different configs out there for different applications. honestly I haven't used one before but from the sounds of it if the wires, and sensors are intact with no CEL's I would think the config on the app. but thats just me

your using the torque app? if so theres a thread on how to get it to read KR.

I've downloaded all of the GM specific PIDs and the Grand prix PIDs as well, i have 3 different knock retard PIDs and none report
I downloaded the knock detector but i think its a dummy test, it counts the timing retard from the pcm as well as load and throttle pos.

i looked at all of the torque app threads and I believe I have it set correctly

I did that to mine when I thought my knock sensors crapped out and I got nothing. Mine later started blipping when the weather changed.

colder or hotter?

I'll find me a 3/4IN wrench and giver a lil smack around and see what happens. Any ideas if it will register if i just smack the exhaust manifold? I'd rather hit there because the knock sensor is right near there.
