knocking and AFR/Lambda don't have anything to do with each other.
the wideband is for checking the exhaust fumes for oxygen, the knock sensor is a microphone (simply said) connected to the engine block.
this microphone needs some electronics (external or internal in the ECU, is stock knock sensor) to eliminate false sounds and get the right knocking and count it.
