So that would explain why the egt sensors are the same in the '15's - it is a pcm issue.
It is possible... but then I have to ask the question. If it is only a computer programming issue, why has Ford been swapping out all of these sensors just to put another sensor in them?
I can't tell from this recall on whether it is an update just to prevent the 10 second shutdown or if in fact it will solve the sensor failures.
If it is software, it could also explain why waiting 45 minutes and then restarting allows you to continue on your way.
It is still too grey for me to agree that this fixes the whole EGT sensor issue once and for all.
Off topic but kind of relates in a way. So the 2011-2014 Explorers have been prone to EPAS failures. Ford finally recalled them late last year but the recall stated if yours hasn't failed yet, you get a software update, if it has failed or has codes in the system from the failure, you get a new $1,800 EPAS.
So owners went in and had the software flashed and guess what.. they still failed afterwards. Not only that, Ford is saying, they honored the recall and flashed the computer so now that it has failed afterwards, the owner is responsible for the replacement.
So although two separate things.. not ready to feel comfortable that this update fixes it.. although if it doesn't, it is still just a $50 sensor, not a $1,800 repair.
