where is knock sensor located on a 99 Silverado 1500 4.3
Looking for the ESC myself....the Knock Sensor wire is blue though.
The knock sensor on that vehicle is located under the intake manifold. The intake manifold must be removed to gain access to the knock sensor.
Trouble code P0330 means: Knock Sensor 2 Circuit (Bank 2) Replace the knock sensor
It doesn't have one.
under he intake manifold
the knock sensors are located in the top of the engine block. The intake has to be removed to get to the sensors.
The knock sensor is on the starter side of the engine. It is abut half way between front and back.
