Sensor unplugged still shows pressure/voltage

--------------------------------------------------------------------------------

96 f 250 7.3 turbo
Autoenginuity scan tool w/ ford software
Factory shop manuals
DTC 1211
I have unplugged the ipc sensor. I do not understand why the scanner shows pressure and voltage readings with sensor uplugged.
I have checked the shop manual for all the tests for shorts and opens.
The duty cycle for the ipr is 12% at a idle and 35% wot.

I have cleared the trouble coded and rebooted multiple time.
Why am getting volts and pressure with sensor disconnected?
