Thank you FX4Offroad. Part KA1Z-5L200-A (EGR flow sensor) did the trick. Runs like brand new! For those of you who have not tried this, it worked. The hose clamp system is an 'ear clamp' system. You will need the ear clamp crimping tool (get the dual front and side jaws), ear clamp cutting...
Thank you for the follow-up and summary. Very helpful as I navigate the exact same issue with my 2019 Ranger Lariat. Can you confirm which EGR sensor they replaced? Was it the pressure, heat, or the flow sensor?
