On pin #6(white/purple) I get nothing which is my bank 2 after cat sensor. This confirms a wire problem. Not sure how I’m going to resolve this. I’ll probably have to bite the bullet and take the car to my dealer. I have no means of dropping the motor and front subframe to access this wire on top of the trans. Bummer!

Thanks, Scrippy, for reporting back and posting a picture of x6200.
Couple of Q's:
1. How are you measuring the voltage? Are you back-probing with x6200 plugged in?
2. Did you try clearing the code to see if supply voltage would return?
These are FET controlled--meaning the DME can turn that circuit off.
3. Did you try testing continuity on pin 5 right to the O2 connector?
This would be a good double-check scenario.
4. Did you also try investigating the DME connector,
X60105?
Does x6200 have continuity to the DME connector? 6 to 44?
