Bank 1 -Knock sensor

[FastStarrCountyL83]

Sup Gentlemen, any of you bowtie guys come across bank 1- knock sensor code on your trucks yet? I installed AFE CAI today, and shortly after took it for a spin, I got a 18 4x4 4 door with 5.3. And it showed a code I believe it was p0235, when I floored it I did notice some noise coming from th engine bay sounded like some sort of short, ran a scan on it and bam it popped that one up. I cleared it but however when the check engine light came on I did notice a slight power loss. It's running fine now, truck has 15k miles on it. Just curious if anyone else has experienced this, I was like whoa knock sensors? Already brand new truck I got it with 0 miles....any info would be appreciated.

there is a tsb on this. carbon build up in the cylinders (under 20k).  My brother in law just got one at 60k with his 2014... 

 

GM says its "Fine, itll go away"????
