Chevy 4.3 Litre 6 Cylinder. Knock Sensor Location

Posted in Crank, Oil and Piston | Asked on Jun 25, 2010

Where can I find it? The obd code reader said it wasn’t receiving a signal from the knock sensor, I bought a knock sensor but where is the old one located on the engine block exactly?

    i’m not positive on this one, but it should be in the intake manifold somewhere.

    If you could give a year/make/model of what this is. I can try to help. I have a 4.3L CPI Vortec in a 92 Jimmy. My knock sensor was on the passenger side of the block a little under the manifold. Can be a real hassle to get out though… Good luck with that…

    The knock sensor is located on the passenger side of the block about 2-4 inches above the oil pan you will see it if you go under the vehicle
