You did have a dark blue wire for the knock sensor, yes?

What does the color of the wire has to do with transferring signal to ECM? I replaced my knock sensor and the wire plug from Jeff Kopp. The wire is white. I too have code 43 everytime the car under higher load

Did you clear the codes by disconnecting the battery for a few seconds?
