Common issue is for the tube to the sensor to be clogged with carbon or possibly rusted out. You might be able to clean the tube with a piece or cable (wire rope) chucked in the drill like a little roto rooter. The tube is not crazy priced to replace either.

Ford wanted a lot for the tube but Rockauto has them. Look for a Dorman # 598-104, I think they called it a "EGR tube". Fit perfectly, $18 and some change, plus shipping brought it to $25.78

Exhaust backpressure sensor tube is F4TZ-9D477-A. Carburetor cleaner helps if you try to clean out the tube.
Dave,
I know there are two different tubes, one which connects behind the HPOP (early models 94-96) and other in front of it (97 - up), and I think that the number of this one is F4TZ-9D477-AA. could you ratify that?

Also I know there are two different numbers for the sensor.

BTW, nashvillebill, the Dorman number is for what: behind or in front of the HPOP?

Thanks for the answer.
Im having searching about of this and I got this from a friend in other forum:
OK here's what I can come up with. I know the OBS up to Mar 97 build date have the sensor mounted above and behind the HPOP reservoir. Mar 97 to the end of 97 may mount in front of the reservoir (my 97 was built in Dec 96 so it is just like my old 94, mounted behind the reservoir). Here's the part number info that goes with that (hopefully correct):

Exhaust Back Pressure Sensor Tube
(Ford) F4TZ-9D477-A, (International) 1821793C1 (94-Feb 97; mounts on bracket above/behind oil reservoir)
(Ford) F7TZ-9D477-AA, (International) 1830933C1 (Mar 97-end 97; may mount in front of reservoir)

There's another part number for the Super Duties (Ford 1C3Z-9D477-AA, IH 1837875C1).....

Also I found myself in a IH catalog this number 1831009C1 for a superdutys ?? so I really dont know about the SDs.
