    knock sensor is tuned to the frequency of the onset of engine knock in the engine it was tested in originally with all of the original parts that engine contains.

    If you changed anything about the engine that the knock sensor was originally designed for it might not work well or at all.
    if you put the knock sensor into anything besides the engine that it was originally intended for it might not work well or at all.

    All engines make noise in varying range of sound and it's how the sensor is tuned to detect specific frequencies which are present at the on-set of knock
