I don't have a diagram but they are under your intake manifold. It's not to bad of a job. You don't have to remove the fuel rails or the injectors, they can come up with the intake. The #2 knock sensor is the one in the rear. I will suggest getting both of them and also the harness and do it all while you have it apart. I believe you will find that water has gotten down in the hole where the knock sensors are located. Make sure to clean it out very good with compressed air before you install your new knock sensors.

It could be that your knock sensor circuit is working perfectly.You may have a knock that it is reading for long periods.
Try running it disconnected, and see if there is a clatter or knock when accelerating lightly.

You could have a vacuum leak.

Where is the knock sensor located in 2000 chevy 5.3 v-8?


They are located below the intake manifold, you may have to remove the intake to change them. The sensors may be shot, they have a problem with water puddling in their mounting wells, after changing, seal the sensors with an RTV to keep water out of the wells

The Knock Sensor (KS) system detects engine pre-detonation. The Powertrain Control Module (PCM) retards the spark timing based on the signals from the knock sensors. The knock sensors produce an AC voltage when specific frequencies are detected. The knock sensor voltages are an input to the PCM. The amount of AC voltage produced is proportional to the intensity of the knock.
When you ****** timing fuel mileage goes down.

Knock sensor location


The knock Sensors are located under the Intake Manifold at the top of your engine. The top will have to be taken off along with the intake manifold. Knock Sensors in past silverados used to have a problem with leaking water that corroded the sensors from washing the engine. Most times when you go to replace the knock sensor you will have to replace both along with the wiring harness that includes the the gaskets the knock sensors are surrounded by. After that you have to check the resistance to make sure you dont have any problems and then reinstall all parts along with a new intake manifold gasket. A good mechanic can do this for you in a day and charge you around $400. If you try to go to some place like a chevy dealer you will pay over $800. This is from experience of just replacing mine 2 weeks ago.
