What is a DPFE hose?
(a.k.a. DPFE Hose Kit) features a two-piece aramid silicone design. The exhaust gas recirculation (EGR) pressure feedback hoses connect the DPFE sensor to the vehicle’s EGR valve between the intake and exhaust manifolds.
What type of sensor is a DPFE sensor?
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 DPFE stand for on a Ford?
Differential Pressure Feedback Electronic
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.
How is the dpfe sensor connected to the inlet manifold?
In terms of operation, a DPFE sensor measures the difference between the pressure in the exhaust system, and the inlet manifold via two pressure hoses that are connected to the sensor, one on either side of an orifice in the tube that feeds the EGR valve with exhaust gas.
What does dpfe stand for in Powertrain Control Module?
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.
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 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.
