Why does exhaust gas recirculation pressure feedback sensor blow the hose off?
You have restriction in the exhaust somewhere and it's causing it to backflow.
What is DPFE sensor?
Dpfe sensor is the delta (differential) pressure feedback egr (exhaust gas recirculation) it monitors the pressure on the egr valve to make sure it is working.
What does the differential pressure feedback exhaust sensor do?
This sensor varifies flow of the exhaust gases to the intake manifold. If flow is interupted the sensor will inform the onboard computer that the exhaust recirculation system has failed resulting in a check engine light to come on.
Where is exhaust back pressure sensor on 2006 6.0 diesel ford f350?
The exhaust back pressure sensor on a 2006 6.0 diesel Ford F3 50 can be located near the exhaust manifold. The sensor is a probe that can be removed by loosening the nut.
What does Ford Diesel Diagnostic Code PO470 mean?
A Ford diesel diagnostic code P0470 means there is an exhaust pressure sensor malfunction. This may be caused by faulty exhaust back pressure sensor, or pressure sensor is open or shorted.
How does one remove a pressure feedback sensor from a 91 Lincoln town car signiture?
Is there a differental pressure sensor in 91 towncar
Where is the differential Pressure Feedback exhaust sensor located in a ford econoline e-150 v-6 van?
AnswerThe DPFE sensor is located next to the EGR vacuum regulator. The DPFE sensor is a rectangular box shaped sensor, held on by 2 nuts. It has two exhaust lines going to the EGR tube. This sensor is on 1996 and later models. joedi (edit: changed 1997 to 1996) joker_102877
Where is the oil pressure sensor located in Toyota surf hilux?

What type of sensor is used to determine the oxygen pressure in the exhaust manifold of automotive fuel injection system engines?
Oxygen sensor
Where is the manifold pressure sensor on a Mercedes vito 110cdi 2001?
Right below the engine on the exhaust pipe.
What is a p1401 code on a 2000 Lincoln ls v6?
P1401 is DPFE Sensor Circuit High Faulty Differential Pressure Feedback Electronic (DPFE) sensor. Loose of disconnected wiring to the sensor
What causes raw fuel to come out the exhaust manifold?
mass air sensor or purge valve sensor could be a bad fuel pressure regulator
