Where are the 02 sensors located on a 2002 z71 Chevy Silverado 5.3 liter v8
Just follow your exhaust from the manifolds to the muffler. You will see them. I can't find a diagram for your year, but should look similar to this.
Here's a better one. Not sure what year. But it's for the 5.3.
Aight thanks for the help!
