6.7L Power Stroke Engine and DrivetrainDiscussion of the 6.7L Power Stroke diesel engine and drivetrain in the 2011-Up Super Duty trucks. No gas engine discussion allowed except on transmissions and drivetrain that pertain to all models. Please confine discussion of topics in this forum to those items that are specific to the 6.7L Power Stroke engine.
Is it too much to ask for Ford to come up with another idea than total shutdown of a vehicle for a simple fault like an EGT or a transmission issue?
Nothing like driving my $60k+ truck home and calling roadside assistance since the programs leave me stranded in suburbia Boca Raton at 7:00 at night.
Thank the dear Lord above I was not in a snow storm on the side of a mountain in Colorado where I would have froze to death due to the fact that some engineer/ programmer had this brilliant misconception on how to build it "FORD TOUGH". Shut it down and don't restart. Give that man a raise!
in the 6.4 that will happen but after 30 mins it should restart. There is also a jumper wire off the passenger side battery that you can use to restart.
Might look into this and see if that is possible

Better it shuts down than burn up. IF there is an EGT failure, the DPF/SCR or cat can overheat. Don't blame Ford, blame your EPA and lawyers who over litigate.

Wrong. If a sensor is so critical that a failure requires the engine to shut down, then the sensor should be redundant. If one sensor fails you keep going on the other sensor with a message to replace the bad sensor.
These sensors are not that expensive. These engines should not be shut down because of one bad sensor.

So which redundant sensor do you believe? The one that reads 600 deg or the one that reads 1400 deg?

In the Ford documentation there are numerous plausibility checks going on between sensors. EGT sensors typically fail with a loss of continuity causing a reading to peg. It would require a software plausibility check between redundant sensors. If one reading is within range of other EGT sensors up or down stream it would be accepted throwing out a sensor displaying an extremely high or low reading.
So with redundant sensors the software would go with the plausible reading based on other sensor readings at the time. Not hard. It is being done elsewhere in the engine.
At the end of the day this is a cost decision by Ford. Rather than cost of an extra sensor Ford has decided it is more efficient for them to shut down the engine and give the owner the job of sorting things out.

And to add to this..in the 6.4 at least alll the sensors are the same part number. Bet they are in the 6.7 as well.
these sensors should throw a check eng light or the wrench and reduce power at most. A message in the message center indicating reduced power because of a sensor reading in the exhaust system. Not that hard.

Good news. The EGT sensor did the trick. However now I have to worry about a repeat occurrence with the other sensor. Anybody know about eliminating the system completely?
Your a little late into the delete phase....the EPA has shut down h&s. From what has been posted any further tuning will be dpf on tuning. You might call around and see if you can find anyone with kits still in stock, get ready to pay for them though. A buddy of mine bought the last two kits around here and he paid over msrp.

Thanks for the reply. Is H & S a company that made these parts if i google search? Sorry for ignorance. dpf?
They were the leaders... I believe there are other companies, I haven't researched it much as I have no plans to delete. I believe edge makes tuners, they are dpf on tuners. Unfortunalty between he EPA and manufactures tuning will soon become a thing of the past. We will be stuck with unreliable overly complicated engines. I have bought my last diesel, they are not the reliable high mileage engines they used to be.
Maybe the aftermarket guys can figure out better states of tune and regen cycles since they will be forced into "tuning" with the emissions controls in place. No reason why we can't have the best of both worlds. Of course, it definitely would be simpler without the DPF and the EGR equipment. Just my 2 cents.
