My dad has an 02 Chevy Trailblazer that keeps
giving code P0502. The code is for the VSS and
this has been changed but still getting the same
symptoms and code. HELP!

Have you ran a circuit check from the VSS to the Speedometer and then to the ECM? A bad speedo can also cause this code cause the pluses have to pass through there to get to the ECM.

How would I perform a circuit test?

Digital ohm meter on the VSS circuits, the pin numbers and locations will be in the shop manual if you have a good one.
