I recently found the old knock sensor I replaced in my car, although I never knew whether or not it was malfunctioning or not, I was just throwing parts at the problem. Anyways, I was wondering whether there was any way to test the sensor out of the car. I read about how the sensor works but could not figure out how to test it. Is it possible to do with a car battery and analog multimeter? If it is, could anybody tell me how it all hooks up?
Thanks

 

Nevermind that question. My multimeter just wasn't working

 

do you know how to test it?
