Regal tossed this code on Friday.
First rule of codes, clean and watch for them to come back. And it came back.
Looked up the code in GM ESI: Says to check wiring, find short and fix the wire basically. Thinking back to working on my car, I didn't route the rear knock sensor wire properly and ehhhh it's been 2+ years w/o any issues. Then I dug more and found out KS2 is the front sensor. Front and rear sensors are different codes and different wires. Being a single wire, this can't be a shared power etc issue. Plus reading up on how they use AC and monitor noise etc.. power/ground related doesn't seem to make sense.
Being lazy, I looked through the passenger wheel at the differential, and sure thing that knock wire was laying on the axle where it goes into the diff. I turned the wheel, reached in and moved the wire. Nothing too technical here because I didn't have any jacks/ramps to go underneath the car.
Code hasn't returned and I am watching for it. It is odd that wiring on the rear was tossing a code for the front. Either that or something bounced up off the road and hit the front, then by luck when I messed with the rear, the front fixed itself. I'm aiming more toward the rear grounding on the axle and pulling the power down. Somehow the pcm must have seen lower input at the KS2 sensor.
