I am getting the "Service Park Assist" on my 2012 LTZ DIC display.  I have cleaned the sensors and checked all the connections.  I see the part number for the park assist sensor listed as 15239247.  Does that mean that these off of ebay will work:

The color seems close enough to white diamond or maybe I can just get some touch up paint.

Is there any way to check these with an ohmmeter or just check the bus voltage to them? The vast majority of other postings seem to indicate that these just fail, often the outside ones.
