Answer
The knock sensor is located under the intake manifold, the sensor itself is almnost never the problem, check the connector located on the left side of the engine, it's located just under the intake throttle body, make sure it is connected, this is especially true if the cylinder heads have been off recently because someone may have forgotten to connect it.
