Solved What is this part?

[Deleplank]

I was under the hood of my 02 Explorer 4.0 and noticed this part. I am not a mechanic by no means but I can fix things if directed in the proper direction. It appears to be melted and looks as though it should be bolted to something but it isn't. I appreciate all help in advance.

It might be the DPFE sensor. It's hard to tell from the picture.

What does the DPFE sensor do?

 

[BrooklynBay]

It monitors & controls the vacuum flow to the EGR valve. Do you see a hose going into the EGR valve? They get ruined when there's moisture in the lines. Do you remember the MAP sensor on the older 3.0L engines? That's was used before the DPFE sensor started to be used on the 4.0L engines.

I couldn't tell you for sure.

It's the DPFE according to this link: DPFE Sensor and EGR Information - Focus Hacks

That is it! Thanks BrooklynBay.
