Hi,
Can someone tell me where the anti-knock sensor is on a 2001 Chevy Silverado? Also, is there a way to test the sensor or do I just replace it?
Thank you!

 

5.3 liter? If so under the intake. To test you need a DVOM set on the AC voltage scale. Put the red wire on the knock sensor and the black wire on ground. Tap/ hit the engine block with a metal hammer as close to the sensor as you can. If the sensor is working it will generate AC voltage the harder the knock the higher the voltage.

 

Thanks MDTahoe I'll see what I can find. randyrt
