Denso MAP sensor testing

[John5788]

Does anyone have data on how the Denso MAP sensor works?



I can't find information on how this thing works but I was just playing around with it and discovered some values I would like to confirm.

Pin 1 - Purple stripe gray wire - Signal
Pin 2 - Brown - Ground
Pin 3 - Red stripe green wire - 5V

Atmospheric pressure = 3.755V
~25 in Hg vacuum = 0.700V
~20psi pressure = 4.90V

Positive correlation between pressure and voltage. As pressure goes up, voltage goes up and as pressure drops and vacuum is introduced, voltage goes down? Does this sound right and do my voltage ranges seem correct?
