I believe all DPFE units have the same output.
You will want to first verify that the EVR is working. The EVR provides vacuum to the EGR valve.
Put a vacuum pump on the intake side port of the DPFE and use a meter to verify the following KOEO :
Pressure ---- Voltage
---0 PSI --- .45 volts
-.50 PSI --- .90 volts
1.00 PSI --- 1.40 volts
1.50 PSI --- 1.90 volts
2.00 PSI --- 2.40 volts
2.50 PSI --- 2.80 volts
3.00 PSI --- 3.30 volts
3.50 PSI --- 3.80 volts
4.00 PSI --- 4.25 volts
4.50 PSI --- 4.60 volts
The table is pressure across the ports, so since the exhaust manifold port is at one atmosphere use twice the inches of mercury on the intake side port.
