Hi,
This code is set when there is low or high voltage sent from the knock sensor. Since the module has been replaced, chances are either it is a wiring issue or the ignition control is bad (part of PCM).
If you look at the attachments below, they provide the diagnostics for determining if there is a voltage issue or if it is a sensor. Since the code is still present, you can most likely skip step one and jump to step 2.

Let me know what you find or if you have other questions. Also, the directions below are for a truck having an automatic transmission. If your vehicle is a manual, let me know. Also, the third pic is more or less a description of the circuit and what causes the code to set.
Take care,
Joe
