Having an issue getting any reading from Rev. P sensor

I am not able to get any sort of a reading on my Rev. P sensor using an Arduino Leonardo. The readings i am getting go from Nan to 1551 mph, and the temperature always stays around -25 degrees C. I am powering the sensor using a 12 volt DC signal rectified from 240V AC (i am the computer engineer on this project so if more details on the circuitry are needed i can ask my electrical engineer). I am not sure where to start trouble shooting, could it be how it is getting power? I heard some people say it could be how it is grounded? Any help would be appreciated.

ajd888,

Do you have the grounds from the power supply and the Arduino connected together?

I will check that out with my electrical engineer.
