need knock sensor expert help with 332 327 codes
I have a 2007 lq4 with a magnacharger on it and I started getting the 332 327 codes for knock sensors. I did install a/c delco knock sensors with a dorman harness. Wiring checks out ok and resistance checks out ok on the sensors. Added grounds and moved my alternator wiring and codes remained. I then took my old wiring harness with old sensor and screwed them into the right front cylinder head. then plugged them in and drove it. I have not received the codes since I moved the sensors. Has anyone else received these codes with a magnacharger. I am wondering if it picks up something from the supercharger that is causing codes.

engine is stock with stock everything except for supercharger. It is a very quiet engine especially compared to other lq4 engines I have had with noisy lifters that never had any knock sensor codes.

I know in the past people have had issues with the Dorman harness as well as anything but OE Sensors.
I replaced mine with the Parts store brand and it failed 3 months later. I went to the junkYard and got a used one and no more issues.
Parts store brand looked like and OE part that was reboxed. I don't know if there handling them different or what. Maybe it took a rough ride.
