Knock sensor question

[Chevyracincamaro]

anyone know what the internal resistance of the knock sensor on a 97 civic is supposed to be? also, where is the sensor?

nobody here knows or has a resource?

The knock sensor should be in the middle of the engine (back).
Ok, I've been reading around to try and find an answer for the resistance thing, and I came up with some strange info (aka; not sure about it). I read that there isn't a resistance value for the sensor at all, and that it either has continuity or it doesn't (works or doesn't). I'm sure that doesn't help much. Here's a screen cap of the service manual of how to test it (again it gives no resistance value): http://img.photobucket.com/albums/v4...nocksensor.jpg
Hope this helps, I myself am not familiar with knock sensors (as my car doesn't use one).

I thought it was a Piezoelectric device, generates a voltage or pulse. ?????

[CivicSpoon]

Yeah that's what I read, it generated a pulse. Like I said, I'm not familiar with knock sensors at all and that info was just what I found over at honda-tech
Here's where I read it (posts 12-15 on that page): http://www.honda-tech.com/zerothread?id=735196&page=4

i wasnt sure if the sensor was piezoelectric or not, assumed it wasnt from readin somewhere. either way that document you linked to seems like it will help. ill take a look at it and see what happens. thank you much for the info guys...
