Default Knock sensor woes

Hello friends,
back in 2021 I had to change my knock sensors and then they went out again a couple months later and I took it to a mechanic and he changed the sensors and valley cover gasket and it was fine for awhile but now my sensor triggered the check engine light again and I’m wondering if maybe there’s a known issue that has an easy fix. I plan on changing the sensor on Friday so any advice would be helpful.

thanks for your time,
- Will

First you need to check the code. ...but I can tell you from now. Don't buy AC Delco brand because they are defected from the manufacturing ... Buy the NAPA knock sensor with NAPA harness are good to go ...

Torquing to the service manual spec is imperative.
