What and Where is My DPSE Hose on My Escourt?

Question

Autozone code check indicated it was disconnected but no one knows what it is. Ford Escourt

Answer 1

It is a DPFE sensor (Differential Pressure Feedback Electronic Sensor) , and the sensor is at the top of the engine, near the EGR valve. it is about half the size of a pack of cigarettes, made of aluminum, and has a connector with three wires at the front of the sensor. If you look closely at the bottom of the sensor, you will see two small hoses that connect at the sensor and run down to the exhaust pipe. Chances are that the hose(s) either rotted from the heat, or have been disconnected accidentally during maintenance or repair. It is best to replace the damaged hose(s) with heat safe hose like silicone hose, or go to Ford for the correct material. Regular vacuum hose or fuel hose can't stand up to the heat.
If the hoses are good and in place, inspect to determine that both hose nipples at the exhaust pipe are clear and unrestricted. You can use a piece of coat hanger wire for this.
If all of the connections, hoses and tubes are in good order, you most likely will need to replace the DPFE sensor. You must get it from Ford, as NONE of the after-market parts stores even know what it is, never mind have access to it. You can expect to pay ~ $80.00 to $120.00, and might have to order it.

Answer 2

Ironhand is correct all the way.

Just wanted to add, that there is a few codes that will set and will assume the DPFE hoses are disconnected if the voltage doesn't change correct (OBD 2 cars have this..it's a manufacturer code)

But instead of just replacing the hose, I'd recommend the sensor and the hoses as , the sensors were known to be trashed sooner or later and the hoses can break by them selves.

The DPFE is basically a common item at Ford Dealers and the base number is 9J460... The hoses are 9P761

and he was correct on the prices, but lately been closer to $100-$120

Surprised Autozone didin't know what that was... they oversell EGR valves because they don't sell the sensor

Answer 3

First of all it's abbreviation is DPFE not DPSE and no code will tell you the hose is disconnected. Second of all if you take any advise from Auto Zone Idiots you get what deserve. The code it gives you is not always the problem ,but that what you can expect from a parts store. Take your vehicle to an auto technician and have it properly diagnosed.

Answer 4

Between the DPSE and the EGR valve.
It helps regulate EGR flow by allowing the DPSE to "view" EGR action and relay that info to the ECU.
It's probably not disconnected but broken or the DPSE is shot.
