Knock Sensor Location?

Where is the knock sensor located? Does anybody have a picture of it's location?

I bought a new one, just for same measures, but I can't seem to find it. :(
 
you can barely see the top of it ..rear top of right valve cover

i can get a better pic tomorrow if you need. i have rags and a spare intake to keep dirt out of my motor till my intake gets back. anyways no problem for the pic.
 
so the threaded hole in the back of the engine that you can see the flexplate is where it goes? the hole that i was arguing with my stepdad over that the knock sensor go into? i was right? ;)

Torqued to 14ftlbs, no more, no less. No thread tape.

I replaced the knock sensor last night. It was right under the coil pack like Grumpy said. What a PITA to take it out with everything in the way. I just tightened it down, but didn't torque it to 14ftlbs. Will that be an issue?

I haven't driven the car yet, but then again, it wasn't reading any knock with the old sensor, that is why I wanted to replace it.

Yes, it needs to be properly torqued to function right. I believe if its too tight, it will be too sensitive.

i would torque it down if you can but i remember i had the same problem sometime back and ran it that way for years.
 
You guys correct me IF I'm wrong. The knock censor reads harmonics thats why no tape. Proper torque is very important on here if it's to loose it doesn't see enough vibration and to tight it will see too much. Knock produces a very specific harmonic "signature" and if the censor is to tight/loose it will either not register it or it will register other harmonics as knock/detonation. Good luck my motor is getting a brand new one in the rebuild while the motor is out of the car. Jon Hanson
