What is a Knock Sensor?

What is a Knock Sensor?
Ok. I jinx'd myself last night .. i told me dad my car was running beautifully and then today i get a CEL. It turns out to be a 0304 which is the knock sensor. Now when i did a search i read a few threads about people who take their car to a mechanic and they say it's a bogus code ...
what i want to know is, where is the knock sensor? and what is its purpose on my car?
I did a search and came up with nothing so don't say anything

If you don't have any other codes, change it, if you do what are they. The sensor is under the intake manifold, my haynes manual says you have to take both the lower and upper manifold off. Screw that, if you have small hands or know somebody who does, you can reach in there and get to it with a wratchet(12mm socket). You can get a wrench with a pivoting extension but I couldn't get the damn thing to tourque(there wasn't enough space).
Don't flame me sprint...we were both right

my KS code first came in combination with the rear heated O2 sensor code, then they both went away.
it came back along with the ECTS code. i replaced the ECTS and both codes went away.
now it's back along with some other oxygen sensor code (0707 i think?). i guess this time i'm going to break down and spend the money on a damn KS. maybe that will finally cure it.
speaking of which, anyone purchased a KS sensor RECENTLY at a good price? any suggestions on current specials would be much appreciated.

The CEL usually doesn't light for a knock sensor; I bet the 0304 code is still there. When you push pedal aggressively and hold it to accellerate, does it surge or feel like the power isn't a constant hard linear pull, like something else is modulating the gas pedal? It's the KS.

That is exactly how my car felt before I changed it(the CEL did light for me) I had "bumpy" acceleration and loss of power.
and sprint...that kiss can go to my butt ...J/K

I just bought one from Jerry Rome Nissan for $120 shipped. He put in the order on Monday, and in a few minutes I had recieved a tracking number, and the part came in on Friday. Check the group deal section to contact them. Ken was who I delt with.
