What to do if your dpfe sensor is bad?
Remove both hoses from the DPFE sensor then re-attach the hose that used to go to the EGR Valve, to the “Ref” hose port on the DPFE Sensor. Doing this sort of tricks the system so that instead of opening the EGR valve when the PCM sends the signal, it will now apply vacuum to the “Reference” sensor for the DPFE.
Where does the dpfe sensor come in a Ford F-Series?
Generally speaking, it is located on the car’s firewall. There’s another hose in there that goes to the EGR Valve. Now, the aforementioned vacuum pressure is used to open the EGR Valve which, in turn, allows exhaust gases to be pulled from the exhaust, past the DPFE tubes, and back into the intake manifold. So where does the DPFE sensor come in?
What should the voltage be on a Ford dpfe?
Allow the multimeter to register the voltage. Ford DPFE sensors should read between .45 and .55 volts. All other makes should read between 0.8 and 1.0 volts. If the sensor is not within the appropriate range, the sensor is faulty and should be replaced.
What does the dpfe sensor tell the PCM?
The DPFE sensor registers this difference in pressure and can tell how much exhaust gas is flowing through the EGR system. It then tells the PCM, if you will, how much gas is flowing through the system, and the PCM uses this data to control the actuator.

Where are the vacuum hoses on a dpfe sensor?
The sensor is a small square with two vacuum hoses on the bottom and a wire harness coming out from the side. The location will vary slightly from make and model. Check your repair manual for exact location and a detailed diagram. Disconnect the two vacuum hoses from the sensor by giving them a firm tug. Turn the ignition key to the “On” position.

What does dpfe stand for in powertrain sensor?
What is a DPFE Sensor? DPFE means “Delta Pressure Feedback of EGR”, Delta means “difference” or “change”, so the DPFE Sensor reads changes in the pressure of the EGR system. What is a DPFE Sensor? The DPFE Sensor tests the amount of emissions being sent back into the system and communicates with the Powertrain Control Module.

How to test the dpfe sensor on a Ford multimeter?
How to Test the DPFE Sensor. Clip the positive (red) lead to the DPFE sensor signal wire. The sensor has three wires; the signal wire is the first wire on the left of the unit. Allow the multimeter to register the voltage. Ford DPFE sensors should read between .45 and .55 volts. All other makes should read between .8 and 1.0 volts.
What should the volts be on a Ford dpfe?
Ford DPFE sensors should read between .45 and .55 volts. All other makes should read between .8 and 1.0 volts. If the sensor is not within the appropriate range, the sensor is faulty and should be replaced. Johnathan Cronk is a freelance writer and began writing at the age of 18.
