That is how it works as long as it was a failed sensor.

Yes, and as others have posted. Remove all four sensors now and apply high temperature anti-seize to the threads. This will make removal painless in the future.

Had a failure Saturday. Long story condensed:
Decided to take the 11' over the 13' because of the truck shell. 850 miles from home the check engine light comes on. Checked the gauge mode temps were OK and truck was running great. Decided to continue to drive(only 4 miles from a destination) as we pulled into the parking lot the motor shuts down in safety mode. Went to start and would not turn over. So, stranded in FL, called Ford Roadside for a tow to nearest FORD dealer. Today is now Monday when they open. Drove a rental in to the department and gave rundown of events. They were able to get me up and running in 7 hours, on a Monday. EGT sensor went out and they were able to replace it, also filled the coolant reservoir and replaced the particualte filter.
FIRST time I have been let down by a FORD diesel. Had an 04', went to Durajunk from 09-late 10, new ford 11 350 Lariat 6.7 and love it. Bought a 2013 350 Lariat 6.7 last xmas. Really concerned about this EGT problem and the engine shutdown, scary *** hell and never know when the others will fail and where. Now I can get my family back home after a 3 day layover.
My other concern is the coolant reservoir was empty on Saturday when I popped the hood. Wouldnt this suggest an EGR problem?

Keep us posted on the remedy. With all of the known radiator failures in past models I really had hoped this issue was corrected. I really don't think the radiator is something you skimp on. For the additional cost associated with this 6.7 motor, the damn thing should be the best money can buy!

Also... my EGT sensor emergency kit is in the truck
1 - CTS or other OBDII reader to know which sensor has failed (sensors are numbered 1-4 front to back)
1 - spare sensor (2 if you feel unlucky)
1 - 13mm box end wrench (flare wrench would be better)
1 - pair leather gloves (or wait for an hour till the torpedo cools down)
1 - denim jacket (or wait for an hour till it cools enough to reach above to unplug/plug the connectors)
1 - tarp to lay on (always in the box anyway)

I've done the anti-seize compound.

I did this also (anti-seize). Although pulling the sensors was easy enough, getting to the connectors was much more difficult. They are tucked into the frame rail. A tip that some may find helpful is to identify which plastic push anchor holds the cable to the frame and push it from the outside in. The cable has a loop and will have enough slack to drop below the frame. You can then unplug the sensor from below the frame without trying to do it inside between the frame and DEF. After you make the new connection it's easier to reach back in and push the anchor back into the hole. The last picture below shows the anchor I'm talking about.
