2001 taurus 3.0 code p0401

Im having trouble with this the dpfe sensor should have .9 volts on pin #1 12 volt ground on pin#2 and 5 volts on pin #3. I have 5.04 volts on pin #1 pluged in and unpluged I dont know where pin #1 gets its feed could it be a bad pcm? I need some help.I tested the egr it test ok I also tested the vac switch it test ok

To me it looks like the power is coming from PIN # 90 on the PCM which is the VREF, which goes to TPS, to the DPFE and to the Fuel Tank Pressure Sensor. I believe that should read 5 volts on #1. #2 should read 0volts and # 3 should read .5 to 4.5 volts.

Here is aa link that migh be helpful to you.
