I finally got Isabel at CS to talk to an advocate, who said the part wasn't covered but they would pay for it anyway. FCA needs to get there act together around this issue. There should be part numbers for the covered parts published so we can all understand what these item actually are. As I see it the Exhaust Pressure Sensor and the Exhaust Manifold Pressor Sensor are the same thing. I looked at the parts diagram and the part number they gave me went into a metal tube, then into the EGR system as part of the exhaust manifold. There is no other Exhaust Pressure Sensor on the truck that I could find. This semantic difference makes it very difficult to understand what was covered and what is not covered.
I would like to thank Isabel at CS for helping me. She listen and advocated for my point of view.
