Can you drive without a DPFE sensor?
You shouldn't drive with a faulty DPFE sensor. If you are noticing a rough idle or a lack of engine power, it's best to replace the DPFE sensor and EGR valve. Leaving the car with a faulty EGR system only causes trouble passing emissions tests and leads to further air pollution.
Which manufacturer uses a DPFE sensor?
MOTORCRAFT® DIFFERENTIAL PRESSURE FEEDBACK (DPFE) SENSOR
The PCM uses this information to control the EGR Valve and other factors to optimize engine performance and emissions. Motorcraft® DPFE sensors are the only ones recommended by Ford Motor Company for use in Ford and Lincoln vehicles.
Where is the DPFE sensor located?
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 DPFE stand for on a Ford?
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 is an EGR sensor?
The EGR position sensor detects the movement and position of the exhaust gas recirculation (EGR) valve pintle. The EGR pressure sensor detects exhaust gas flow through the EGR passage.
What is a Ford EGR valve?
EGR Valves are designed to reduce Nitrogen Oxide and to reroute as much harmful gases back into the combustion chamber, which cools the gas in combustion engines. ... We offer fast shipping on all in stock Genuine Ford EGR Valves and a Nationwide Ford Factory Warranty.
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.
What is DPF pressure sensor?
A diesel particulate filter (DPF) differential pressure sensor measures exhaust backpressure and signals when the power-train control module (PCM) should begin a regeneration process to clear the filter of diesel particulate matter (DPM), or soot.
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 ...
What would causes a DPFE sensor to melt?
The delta pressure feedback of EGR (DPFE) sensor was burned up for having too much back pressure on the engine. ... As the pressure builds up, the engine exhaust temperature rises and will heat us the tubes that the DPFE registers and will cause it to melt.
