May be a problem with the knock sensor or the wire to it.
With the connector off the KS, check for 5v on the harness terminal with key ON. Continue if that is good.
Key OFF. Connector off. Measure the resistance between the KS terminal and ground. Resistance should be between 3300-4500 ohms. If it is not, the sensor is faulty or the sensor is not making good contact with the block.
If all that is good, it might be the knock module or faulty pcm.
