DPR sensor

the Differential Pressure Regulator takes its input directly from the ecu. 
yes its current, but the source is a variable current source inside the ecu 
itself (it does this so that changes in temp do not impact the current 
through the coil - which would impact the linearity of the dpr response). If 
you get 0 mA through the dpr, you can do a rough check of resistance 
directly across the dpr itself. it should be a low value (<20 ohms or so, 
iirc).
