You mean KNOCK SENSOR? its under the intake manifold, replaced both of them AND the harness. Be sure to put silicone grease in the connectors and around the rubber plugs. Water is the number one killer of these.

Need to know how to replace the crankshaft position sensor

Silverado, the crankshaft sensor is located behind the start, you have to remove the start to get access too. Raise the vehicle and remove the right front wheel, drop the start and move forward a little bit, this will expose the sensor
