The knock sensor is resonant to 6KHz...ichh...
It only capture knock ( and some engine noise sometime). I have see old Mopar Service manual that explain in detail the knock sense circuit and there no filtering in the LM SMEC..The ECU Catch the KS voltage.
You can simply read the voltage whit a cheap Meter like i have do..look on this section for more info.
