How does the pressure sensor on a DPF work?
How does the pressure sensor on a DPF work?
These allow the connected pressure sensor to monitor the pressure differential either side of the DPF and consequently calculate how ‘full’ the DPF is and therefore when the car needs to carry out a regeneration.
What is differential pressure sensor Delta-P used for?
Differential Pressure Sensor Delta-P for Particulate Filter Applications The pressure sensor described underneath is mainly used to monitor the soot loading of a particulate filter on a diesel engine or gas turbine. The signal of the sensor is not sufficient to determine an optimized timing for regeneration of the DPF.
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.
Where is the dpfe sensor on the firewall?
Identification of EGR system components On most Foci, the DPFE Sensor is a “Winged” Black box bolted to the firewall pretty much in the top middle, with 2 rubber hoses coming down off of it, and a 3-wire plug going into it perpendicular to the firewall.

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.
