What are the symptoms of a bad DPFE sensor?
Symptoms of a Bad or Failing EGR Pressure Feedback Sensor
- Engine performance issues. One of the first symptoms of a problem with the EGR pressure sensor is engine performance issues.
- Failed emissions test.
- Check Engine Light comes on.
How do you test a bad DPFE sensor?
How to Test the DPFE Sensor
- Open the hood of the vehicle.
- Disconnect the two vacuum hoses from the sensor by giving them a firm tug.
- Turn the ignition key to the “On” position.
- Connect the negative (black) multimeter lead to a ground point, such as the negative battery terminal.
Where is the DPFE sensor located on a Ford Explorer?
The 2005 Ford Explorer 4.0 DPFE sensor can be found behind the upper intake manifold between the firewall and engine block near the EGR valve. The Differential Pressure Feedback ExhauSTSensor, or DPFE sensor, is part of the vehicle’s exhaust gas recirculation (EGR) system.
How much does a DPFE sensor cost?

Can a bad DPFE sensor cause misfire?
When the DPFE Sensor starts failing, it gives the PCM bad information. This excessive amount of EGR combined with the air coming in via the throttle body leans out the fuel mixture, causing a lean misfire, which is the “stumble” or “hesitation” that is common as the DPFE Sensor fails.
Can you clean a DPFE?
I cleaned them both with a wire brush and carb cleaner. Let the entire mess dry out after spraying some compressed air in each passage and cleaning out the tubes as well. The results: Don’t waste your time! Put the DPFE back in and reconnected the tubes and drove the car for 25 miles …
Where is the DPFE sensor located on a Ford f150?
Locate the DPFE sensor. It is positioned to the left of the brake booster up against the firewall and has two metal tubes running from the EGR valve supply line and into the DPFE sensor. Note that some sensors will “float” above the tubes, while others may actually be fixed to the firewall by (2) bolts.
What does a Ford DPFE sensor do?
DPFE (Differential Pressure Feedback Electronic) Sensors are an integral part of the EGR (Exhaust Gas Recirculation) System. The DPFE Sensor provides information to the Powertrain Control Module (PCM) to tell it how much exhaust gas is flowing through the system.
What does the DPFE sensor do?
o DPFE (Differential Pressure Feedback Electronic) Sensors are an integral part of the EGR (Exhaust Gas Recirculation) System. The DPFE Sensor provides information to the Powertrain Control Module (PCM) to tell it how much exhaust gas is flowing through the system.
Can a bad EGR cause stalling?
EGR is used during part to full throttle operation, but never at idle, because it will cause severe engine roughness or stalling.
How can I check if my dpfe sensor is working?
Here are some simple things you can check for yourself with the help of a multimeter and basic knowledge about its use. Check the vacuum hoses: Check for cracks or broken hoses between the EGR and the DPFE sensor. Check the wiring: Use a multimeter and measure the signal, ground, and voltage.
What does the dpfe sensor on a Ford F-150 do?
The main purpose of the EGR system is to reduce the amount of nitrogen oxide that the engine releases during combustion. Ford often uses the DPFE sensor for its various vehicle models. The most common car model is probably the F-150. EGR, which stands for “ Exhaust gas recirculation “, is a mechanism that controls exactly what the name suggests.
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 does dpfe stand for in a car?
DPFE is short for Delta Pressure Feedback of EGR, the purpose of which is to monitor the pressure changes of the EGR. All this may sound very confusing, as even many car fanatics don’t normally hear the name DPFE or EGR, but don’t worry because after reading this you will get a firm idea of this sensor and its function.
