Product ReviewsGM ACDelco 12601822 213-3521 HARNESS KNOCK SENSORS KIT SET LS6 LS7 C5 C6

One sensor not crimped properly

One of the sensor bodies wasn't crimped properly and couldn't get torqued. Pressed edges in vise, still ohm good and installed. This makes me question if they are really AC Delco or possibly 2nds? Bag says they are. Haven't driven much yet but so far no codes being thrown. Also harness needed a small adjustment for plugs to be able to reach each knock sensor.Read full review...

Gm knock sensor harness and sensors

I replaced sensors and harness when replacing with new long block. I checked the sensor ohm value before installing since this is installed under the intake manifold. Everything checked out. I have had bad new sensors beforeRead full review...
