From what I understand , it is the sensor that the Powertrain Control Module uses to determine exactly how much the EGR valve opens at all driving conditions
where is the DPFE sensor located on a 2002 ford crown victoria?
Start by replacing the DPFE sensor. Autozone about $35.00.newtest3
P1401 is DPFE sensor circuit high, check out this tutorial to replace the sensor on your Ford
