2001 Cavalier Z24 Knock Sensor Location?

Hey everyone. I have recently purchased a 2001 Cavalier Z24 with only 84,000km's on it. I haven't been driving it around much at all, maybe a couple hours a week at tops. My engine light kept gogn on and it would stay on for over a week, so I braught it in and scanned the codes and got this:
P0325 Knock Sensor.
I have looked around trying to find the knock sensor location, we have a program called Mitchell's (www.ondemand5.com (http://www.ondemand5.com)) and it says nothing about it on the 2.4L's only in the 2.2L's. I was hoping that someone could possibly tell me in as much detail as possible where it is located so I can run the proper tests on it.
Thanks alot!
