The orifice is positioned between two hose ports coming off the tube which are connected to the DPFE sensor with special heat-resistant hoses. FORD 2002 EXPLORER 40L V6 Exhaust Emission EGR Pressure Feedback DPFE Sensor.
It is common for the sensors to stick at a certain voltage.

Step 1 Check the condition of the vacuum hoses going to the DPFE sensor and the EVR. 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 brownlight green wire. 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. This signal is then sent to the vehicles computer system to be compared with previous readings and used to control the EGR for optimum airflow. The Differential Pressure Feedback Exhaust Sensor or DPFE sensor is part of the vehicles exhaust gas recirculation EGR system.
The sensor monitors and measures the pressure with the EGR valve. This prevents the valve from malfunctioning and allowing too much exhaust into the intake manifold at one time. What is a DPFE Sensor.
DPFE means Differential Pressure Feedback of EGR. Its also referred to as Delta Pressure Feedback of EGR with Delta mean ing difference or change. Regardless of the acronyms definition the DPFE Sensor reads changes in the pressure of the EGR system.
Motorcraft - Original Equipment OE Sensor Assembly Part No. DPFE-4 The only parts recommended by Ford Motor Company for Ford Lincoln and Mercury vehicles. DPFE Differential Pressure Feedback Electronic Sensors are an integral part of the EGR Exhaust Gas Recirculation System.
This video demonstrates how to test and proper. Follow that metal tube and you will see to hoses coming off from it. Follow the hoses up to the DPFE sensor.
It is common for the sensors to stick at a certain voltage. With them unplugged the Computer should default a value of around 5 volts. With it plugged in the voltage should be around 1 volt key on engine off.
Disconnecting the DPFE Sensor Jump to 118. The DPFE Sensor measures EGR flow across an orifice located inside the special EGR Tube. The orifice is positioned between two hose ports coming off the tube which are connected to the DPFE sensor with special heat-resistant hoses.
When the EGR Valve is open a pressure differential is created across the orifice intake manifold pressure vs. By design this difference in pressure is measured by the DPFE sensor in terms of voltage. 2005 Ford Excursion PositionNA 2005-2007 Ford F-250 Super Duty PositionNA 2005-2010 Ford E-350 Super Duty PositionNA 2005 Ford E-350 Club Wagon PositionNA.
And from what I saw people saying the DPFE has a pretty high failure rate and generally anytime you get EGR codes on these trucks its almost always a bad DPFE. And if you read the 335 code on FFI it says PFE or DPFE sensor voltage out of Self-Test range whereas my codes manual just says EGR sensor. The EGR system module ESM is one of Fords latest EGR system for gasoline engines.
It is an EGR valve EVR MAP and DPFE sensor rolled into one package. Though the DPFE sensor on an ESM is referred to as DPFE by the scan tool and also wiring diagrams it is not a traditional DPFE sensor as used on the older EGR system. FORD 2002 EXPLORER 40L V6 Exhaust Emission EGR Pressure Feedback DPFE Sensor.
No parts for vehicles in selected markets. Where is the DPFE Sensor located on a 2003 Ford That is the Differential Pressure Feedback Exhaust - eg. You shouldnt have any trouble finding it.
There is usually a metal tube from the exhaust manifold going to itas well as one or two vacuum hoses. EGR Pressure Feedback DPFE Sensor Connector. FORD 1996 EXPLORER 40L V6 Exhaust Emission EGR Pressure Feedback DPFE Sensor.
