First check the voltage at the knock sensor wire. Should be 5 volts.
Resistance reading of the knock sensor is around 100k ohms. Most knock sensor problems I have encountered are due to a poor connection between the connector and sensor. My suggestion would be replace the connectors on the sensors. A pigtail kit is available from GM parts.
