Low input means an open in a circuit, a high means its got a short.
Why they say input is that every thing is refernced to the ECU, not the individual sensor. A low input means that there is a low or no signal going into the ECU.
There isnt anything earth shattering here. Replace the wires with OE wires, also replace the PCV valve, and check to make sure the PCV valve hoses are not clogged.
Drive the car for a few days, then re read the codes. There is nothing there that is going to blow the car up, but the knock sensor may affect performance, so go ahead and replace that.
