Diagnostic Question

I'll try to be brief. I had a PO36 current code come up. I started following the proceedure, alot of start overs, but I am learning. On the PD07 value I had a 42

reading. From there I am supposed to go to PS02. Where is that and how do you get there from a PD07?

I think you are going too far with the diagnostics. PO36 is a very common EGR code on these cars (or really any GM car).

Cleaning the EGR valve should fix your issue.

The PO36 code went from current to history. Go figure. Still,how would I get from PD07 to PS02? I'm just trying to learn the buttons.

I'll still clean the EGR when I find a how to thread.
