I wouldn't worry about replacing the sensor too much. From everything that I have read on the forums and elsewhere it is not a major code and typically the error is not due to the sensor but something else. Possible culprits are timing, o2 sensors, spark plugs/distributor.... Did you get the knock code along with another code, or was it just there on it's own?
