Replace knock sensor '03 Silverado

Where is the knock sensor located?

Replace knock sensor '03 Silverado

Postby DaveSilverado [OP] » Aug 03 2010, 4:54pm

According to codes my knock sensor is due to be replaced. Since this is my first Chevy I have no idea where it is located. I'm sure it's probably an easy fix; detailed description on "how to" or pictures (location) would be even better.

Many Thanks!
