I dont have a computer. i would simply like to add a knock sensor to my engine, which never had one before. My question would be:

Is it possible to install on an engine which never had one?
What kind of readings does it give? voltage? Resistance? In what ranges?

I have a laptop capable of reading voltages from any source wire, +-10 Volts. Im using it for my O2 sensor i installed, to tell me what AIr/fuel ratio im at through my laptop. Im sure it can be done with a knock sensor as well, i just wanted to know HOW to install it onto the block, WHAT it looks like, WHAT kind of readings does it use etc..

Any information about knock sensors is appreciated.

 

knock sensor usually screws into one of the freeze plug holes on the engine block.

knock sensor is going to give readings similar to what a microphone would. it's going to be a sinewave of sorts with varying frequency and amplitude. even if one connects an oscilloscope to the knock sensor, the readings are going to be of limited use to the average end user.

best bet is probably to listen with your ear. a little detonation is ok, but too much is bad.

don't feel too bad about not having a knock sensor, my 1998 crown vic doesn't have one either. and it's considerably newer than your thirdgen is.
