Reading Code 43

[Artic Typhoon]

I got som problem with knock alert.

I use scan master and read zero knock but, at WOT the car got a 43 code and the boost and timing drop.
I tested my knock sensor with ignition on and by knocking on engine by a tool
the scan master is reading my knocking
Any tips abouth this problem ?

check circuit 496 for open or short. Also check for proper Mem-Cal installation
