Problematic Knock Sensors 2006 Tahoe z71

What’s going on with the knock sensor triggering the check engine light, even after replacement (including wire harness)?? obviously a known issue, has anyone gotten to the bottom of it yet?

yes indeed. i almost always use oem parts if i can. again, according to youtube and other threads it’s a known issue. some ppl choose to bypass the knock sensor altogether
