Problem With Knock Sensor feedback

Hey guys, I am having a wierd issue with my knock sensor. It just constantly reads .2volts, it never fluctuates or anything like that. Is there something not configured right in the EMS. I havent gotten to a dyno yet so the tune is super safe at around 10.5:1

I figured I should be getting some fluctuation of the reading and maybe even more than .2volts since this is a no-balance shaft 2.4 bottom end which tends to me a little more noisy.

Any help is appreciated.

Are you coming to this conclusion by looking at a datalog at WOT or trying to stare at a parameter screen on the laptop while the car is going?

looking at the parameter screen both while the car is not moving at idle, when the car is driving, doesnt matter, always .2 volts. I went as far as powering the car on, motor not running, opening the parameters screen, it says .2 volts still and then I tapped on the back of the block a few inches from the knock sensor with a ball peen hammer, no fluctuation at all.

Obviously the sensor could be bad, but is there anything I can check for in the AEM software that could be wrong.
