knock sensor harness ohm test
 

I have red the 6 page book on here about knock sensor test. but just so im clear .. on the knock sensor circuit .to test the harness to the ecm do I unplug the pigtail at throttle body and just put my leads from my meter on the 2 pins with my digital meter set to "sound" for continuity????? I know I have ground ..that was easy. thank you
