What is this?

[redthunder]

On my 94 X, there is part on a bracket just below the IAC. It has two hoses running from it to the EGR tube. On the part, by the front hose, it has REF. Anybody know what this part does?
Thanks

It's your PFE. It senses what your EGR valve is doing.

sorry.....just gotta know, what does PFE stand for.
Thanks again

Pressure Feedback..............................dunno! (maybe EGR)

On the later years, they were called DPFEs, which were Differential Pressure Feedback.............

if no one else replies, I will try to look it up tonight to tell you what "E" is

that's ok....you don't have to do that, I think you told me enough. I don't think that's going to get me anywhere though.
Thanks Robb
