p0108 Baro Map code even with new sensors

I started out chasing some transmission issues and found that I had a P0108 Baro Map Sendor high voltage code. When I clear the code the the transmission line pressure issues are corrected. The problem I am having now is I have tried three different MAP sensors but I still get the same p0108 code. I have even tried a different PCM and still get the same code. Any help would be appreciated.

One more thing. When I unplug the Map Sensor I get the same code of p0108.

I just found that there is a Barometric Pressure sensor inside the cab that is causing my code. I had no idea this even exsisted. I will have to get one and see if this clears up my transmission problems. When I unplug it I get P0107 code. Thanks and Here's to hoping it corrects my problem. Just for any guys with the same problem in the future I found that the part numbers are F8UZ12A644AA or Motocraft DY-846. Thanks again.

The new sensor fixed all the issues.
