NHTSA probing F-Series with 6.7s
#16
The problem is that the EPA mandates all this stuff, and all these extra components are added to the truck.
Then people wonder why the h*** it breaks down.
I've worked with EPA people in Washington before (long story). These people are completely clueless wanna be do-gooders, but they are making the environment actually worse, not better, by all their regulations.
None of the could possibly understand why anybody who does not have to have a semi and haul 80k pounds would actually NEED a diesel truck, nor do they care.
They think a Prius can be used as a tow vehicle. They complain about garbage trucks being smoky. They complain about garbage doing to the garbage dump.
Ugh....you would believe the stories I could tell you. Maybe I'll write a book one of these days.

The only thing they can't do is ignore the last sensor on the truck because there are no sensors that can corroborate the reading from that sensor.
While I have not yet had the mispleasure of a failed EGT sensor, it has gotten me concerned enough to purchase two spares along with the 13mm flare wrench to keep in the truck.
Hopefully once they dig into this a little further, they will see that it is still the same sensors / problem all the way up the line to the 2015 trucks..

I never had a failure in my 6.4. Never bought a spare sensor either.
But this is a big enough problem that it needs to be addressed.
I have not had any issues in my 6.7 either.
It has the newer style sensor already though.
but still from a programming point of view I can understand they don't want a melt down but they need to build in another redundancy feature to by pass but yet ensure safe operation.

That is another point I made long ago. You'd think they could program it to read other sensors to see if they are too high and if not, just throw a CEL. Not a shut down.

Very true Sam. I guess I should elaborate. Even when measuring the EGT post turbo, they should know the temp range of every sensor at each location and be able to set ranges for each. If the pre dpf failed, the post one should read in its normal range, if not, then throw the code. If the pre one is too high, then you are looking at an overfueling problem of some sort. Like the 'Firebreathing Ford' on YouTube. I hope I am making sense as I am extremely tired...

I agree 10000000% it shouldn't shutdown, and I hope we get a change. I don't know WHY they decided that was what had to be done, but there was a pretty good reason.

It is my understanding, when the '08s came out they did not shut down. Then the infamous fire breather was seen world wide and Ford did a reflash of the PCM as they couldn't handle another fiasco like the bad rep the 6.0 had gotten. So from them on, they shut down when it gets out of range. I've been told this by two different service managers and a couple of techs, but we need one of techs here to verify.

I would think they could put in another sensor for redundancy. If one fails it can read the other and keep going. A code can come on to tell you one went and give you time to prepare.
I know you can weld a bung on the exhaust at other places on the clock for access or redundancy.

we still don't have a double on any production vehicle.. so I'm pretty sure that would not be a path they could choose.
