If the hose connects to the EGR valve than it is the EGR pressure transducer.

It senses when the exhaust has enough pressure to allow sufficient flow thru the EGR valve for proper operation.

Yep, what poorboy said.

There's a diaphram inside that sometimes goes bad and affects EGR operation. Bad news is that it's not available separately from the EGR valve.

Good news is that they is at least 2 in every junkyard I have been to.

Once it's daylight out, I can tell you for sure.

Here is a diagram of where the hoses should go:





So it should go from the vacuum tree on the intake manifold to the vacuum block, then to the egr solenoid beside the air box. From the egr solinoid back to the vacuum block, an finally from the vacuum block to the port on the diagram labelled 'vacuum signal in from egr solenoid'.

The large black multiple hose connector taking up most of this photo is what I was calling the vacuum block. Hopefully it is the right terminology.

The vacuum tree is at the bottom of the photo:

No, I don't think that sounds right. I drew a sketch of where the hoses should go, but my penmanship isn't so great.

If this doesn't work for you, might I suggest you peek under someones hood that has the same year as you. You may find one in the junkyard or somplace.
