How does the dpfe sensor work in an EGR system?
How does the dpfe sensor work in an EGR system?
Well, when gas passes through the EGR tube, the two tubes leading to the DPFE Sensor get pressurized. As this happens, a difference in pressure is created, wherein one tube has more pressure than the other one. The DPFE sensor registers this difference in pressure and can tell how much exhaust gas is flowing through the EGR system.
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.
How does delta pressure feedback of EGR work?
However, the DPFE sensor monitors the pressure difference in the air and the amount of air entering the engine and gives feedback to the EGR system according to the readings, hence the name “Delta Pressure Feedback of EGR”. In a sense, the DPFE sensor informs the EGR system how much air to let in, taking into account the situation.
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?
How is the dpfe sensor connected to the EGR valve?
Basically, follow the EGR pipe until you see 2 metal tubes next to each other split off from it, then follow those to the rubber hoses and those hoses to the DPFE sensor. The EGR Actuator is an electric device that allows small amounts of vacuum pressure to pass on to the EGR Valve.

What are electronic performance parts for Ford 6.0L diesel?
Electronic Performance parts for 2003-2007 Ford 6.0L Power Stroke Electronic Performance Chips, Programmers, Tuners, and Monitor/Gauges for Ford 6.0L Diesel – available from top quality brand… More Details » The fuel system is the very heart and soul of your Ford 6.0L Power Stroke engine.
Can You unplug the EGR valve on a Ford PowerStroke?
Unplugging the EGR works but you can still cause a cooler failure by overheating that small cooler with exhaust gases. There is a better option that requires some work, but works VERY well. I’ll post some links to all this later. Remove the EGR up-pipe, this connects to the EGR cooler behind the turbo.
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.
How many EGR valve Ford 6.0 diesels are there?

Can a check engine light be set off by an EGR sensor?
If the computer detects any problem with the EGR pressure sensor signal or circuit, it will illuminate the Check Engine Light in order to notify the driver of an issue. A Check Engine Light can be set off by a wide variety of issues so having the computer scanned for trouble codes is highly recommended.
What does vacuum pressure do to the dpfe sensor?
Vacuum pressure opens the EGR Valve, allowing exhaust gases to be pulled from the exhaust manifold, past the DPFE tubes, then back into the intake manifold. When gas flows through the EGR tube, the two tubes leading to the DPFE Sensor get pressurized.
On the way up to the EGR valve, the exhaust gas passes through a restriction. The DPFE sensor hoses are connected to ports 1 and 2—before and after the restriction. By comparing and reporting the differences in pressure, the computer can determine exactly how much exhaust gas is flowing through the EGR valve.
