The EGR backpressure sensor / differential pressure feedback EGR ( DPFE) sensor on a 4.0 L OHV engine is on the driver's side of the engine , mounted on the side of the upper "plastic" intake manifold . It is rectangular with an electrical plug in connection on the front and 2 small diameter hoses connecting to the bottom. The rectangular box may be metal or plastic.
I have not heard of such. There is an ERG valve and sensors for oil and smog but not just for position.
The P1405 ERG hose on your Ford explorer XLT is located on the back of the fuel injector pump. The hose goes to the air intake cleaner. The hose is about 2 feet long.
Assuming you mean the egr valve, I would make sure that you have the check engine codes cleared. In addition, are you sure that it was truly the egr valve, and not the DPFE sensor monitoring the valve?
I changed erg valve o2 sensor and gas cap but lights back on what do I do
The EGR valve for the 4.0 L OHV V6 engine is located on the driver's side of the engine - Helpfull
Right on top of the valve cover
The EVP (EGR Valve Position) sensor is mounted atop the EGR (Exhaust Gas Recirculation) valve near the right side of the throttle body (5.0L and 5.8L). The entire assembly is near the front of the right side of the engine. The EVP sensor has a three-wire electrical connector and attaches to the EGR valve with three small screws. The sensor is mounted in the same location atop the EGR valve on the 4.9L (inline 6) however the entire assembly is nearer the mid-point (fore-to-aft) of the engine.
On my ( 1995 ) Ford Explorer with the 4.0 OHV / pushrod design V6 engine the EGR valve is located low down just to the left of the engine oil dipstick ( when you look into the engine compartment from the drivers side , it has a round shaped top on it )

wats ERG?
An erg is a unit of energy equivalent to 10-7 Joules. It is also a dyne centimeter, which is probably the most common expression of an erg. And 6.2415 ×1011 eV (electron volts) is also an erg. A link is provided to the Wikipedia article on the erg.
