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.
