knock module issues
knock module issues I believe my knock module is bad as im throwing a DTC 43 for the sensor and upon further inspection am not receiving 5 volts but more along the line of .01 volts lol, i put a lt4 KM in a while back and sense have had the computer tuned twice by ion at madtuner and have built the lt1 into a 355. my question is does anyone have a lt1 or lt4 KM for sale or is it even worth the time to try to KM because all data said if below 5 volts then it's prob a bad PCM. This is the only code im throwing and i;m afraid its hindering my performance and perhaps hurting the motor. any ideas or that KM to try a working one would be great, thanks.

Have you even gotten a meter out to test the KS wire at the sensor?

D22 on the blue PCM connector (94-97)
(you don't even post what car or year you are working on)
i apologize for the lack of info on that car im used to a few other fourms where its all listed lol. but its a 95 formula auto. im horrible on the electrical aspect of cars, but the 2nd link you provided helps alot. do i have to put the positive prong of the volt meter in the d22 slot or on the back useing the little needle to contact the wire? like posted in the first one i tested the ks and the wire under the car but wasnt aware of which wire it was on the pcm, ill try this as soon as i can.
