What does a DPFE sensor?

What does a DPFE sensor?

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.

Why does the dpfe sensor on my focus fail?

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. The DPFE sensor in the Focus is not very robust, requiring frequent (every 30k miles or sometimes less) replacement or a work around.

What is the dpfe sensor on a Ford F-150?

Ford uses the DPFE Sensor a lot for their different car models. The most common car model is probably the F-150. EGR, which is short for “ Exhaust gas recirculation ” is a mechanism which controls precisely what the name suggests. The EGR system consists of a valve which controls the exhausted air getting back into the engine.

How to replace the dpfe sensor in a focaljet?

Photo of the ’01 replacement DPFE Sensor (thanks to Jaspo from the FocalJet forums): 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.

How much does it cost to replace the dpfe sensor?

This can lead to legal problems and also shorten the life of your engine. Depending on your particular car, replacing the DPFE sensor along with the EGR valve should cost between $150 and $500 including labor, which also depends subjectively on where you live.

What is the function of the Ford dpfe sensor?

Ford DPFE sensor Function. 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.

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 to do if your dpfe sensor goes Kaput?

Work around #2: Take the hose off the EGR Valve like shown above, except then pull both hoses off the DPFE Sensor, and re-attach the hose that used to go to the EGR Valve, to the “Ref” hose port on the DPFE Sensor. This only works if your DPFE sensor is starting to fail but hasn’t gone completely kaput yet.
