What to look for in a Ford dpfe sensor?
Look for cracks or tears. Replace the hose if you find any. Step 2) Check the operation of the DPFE with the engine off, key in the run position. Using a digital voltmeter, check for voltage on the brown/light green wire. Look for a reading between .45 and 1.1 volts.
How does the dpfe sensor work in the EGR system?
In a sense, the DPFE sensor informs the EGR system how much air to let in, taking into account the situation. The DPFE sensor checks the pressure of the extracted air and the pressure changes by means of an orifice. The output that the sensor receives is then converted into an analog signal.
Why is my Ford dpfe not working properly?
Unfortunately, Ford didn’t give enough consideration to the impact of corrosion inside the DPFE, and that’s what causes most of the EGR related problems. Do it yourselfers and professional technicans make an all-too-common mistake if they automatically replace the EGR valve when they see an EGR related code.
What to do if your dpfe reading is outside the range?
If you have 5 volts, and the reading from the brown/light green wire is outside the range, replace the DPFE. After replacement, perform the voltage check again to eliminate the possibility that the EGR valve is not seating properly. Step 3) Leave your meter connected and start the engine.
Where is the dpfe sensor on my car?
Locate the DPFE sensor, which is near the EGR valve, behind the upper intake manifold, between the firewall and engine. 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…

Is the dpfe sensor called delta pressure feedback of EGR?
As we just mentioned the name, the DPFE sensor is called the Delta Pressure Feedback of EGR. We will talk about EGR later. The DPFE sensor is one of the components of your engine that is there to monitor all the air that is going back in the air intake from the exhaust. Yes, you heard it correct.
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.
