What is the "ORN/BLK PCM 34 PNP Switch Signal" wire for?

It's a park/neutral position switch wire, it's supposed to see ground in park and neutral. I believe it bumps the rpm up a little when you shift into drive, and they tell me that if you ever have to do a "crank learn", the pcm has to see that the car is in park or neutral.
