For those of you inquiring information about the EVO sensor. It is also known as a steering wheel position sensor, and it took me no more than an hour to replace. It cost me approximately $73 at the dealer after tax, but if you visit www.gmpartsdirect.com you can find it a bit cheaper. I emailed gmpartsdirect and received a reply after I had already purchased the part from the dealer. Here’s what was sent to me from a gmpartsdirect rep:

EVO sensor is also referred to as a steering wheel position sensor, VSS is for the transfer case.
