Onboard "toolbox"
Hello all. I believe I am now almost there with my onboard toolbox recommended by many for at least the '11s and 12s. I purchased a "BAFX Bluetooth OBD2 scan tool" (Android) from Amazon for $24 and downloaded "Torque Pro" for my phone and Android tablet. I plugged the scanner in, brought up the software and was able to "read" the truck. I was happy to see there were no existing fault codes when I checked that screen. Yesterday I ordered an EGT sensor (part# AC3Z5J213B) for $42 (checked with local dealership first and they wanted $74 for the same sensor) and I have a 13mm wrench in hot stand by. All of this will go into the compartment under the back seats, so...I think I am almost there. So...last question- when/if I get the "Stop Safely Now" message and ultimately pull over somewhere to plug in the scanner (and wait for the cool down), will it be easy to verify which EGT sensor is bad? It appears that it is normally #4 that is causing issues, but want to make sure I am replacing the right one. Another reason I did all this is because it seems like whenever I am "ready" for problems, they tend not to happen

The scanner will tell you which sensor has failed, and if you want to test just to be sure, unplug one with the key on and see what comes up on the scan tool. Should read like an O2 sensor, bank 1 sensor 2. Bank 1 is cylinder no.1 side on Ford it's the drivers side. sensor 1 is the first 1.

Thanks Larry and Dakster! I had not heard or read that the new flash was supposed to take care of the message. Was it also supposed to fix the truck "dying" shortly thereafter?
I know the HTSB is still looking into why Ford recalled the ambulance trucks for this issue and not the consumer trucks.

FYI:
It is a good thing to test verify like the member has posted. The thing about using Torque Pro is that different people used different names for the EGT sensors locations. The EGT 1 location with the Torque Pro Custom PID I use might not be the same as yours?
If you monitor the EGTs with the graph display with Torque Pro, this might give you a better understanding of the locations. From a cold soak by theory the EGT closest to the engine should heat up first.
Also I believe that the Nox sensor should not read like an EGT sensor. EGTs are a RTD device and the Nox/O2 sensors are not and have heater circuits.
I'm not an Expert and I'm guessing. I believe that the new flash reduces the temperature of the active Regen. I don't know if it will change a measage or stop the engine, that is a software thing? If you have to change a EGT it is a hardware thing, I believe that thermal shock is causing the RTD to fail, but it can be that it is just a man made thing breaking.
I have graphed the EGTs and one of them had a noisy signal before the flash and it doen't appear to have one after the flash. I guess time will tell.

also, if you DO get the stop safely NOW message, there should be a code recorded and it will also map to a sensor.
from https://www.ford-trucks.com/forums/1...l#post13833260
bank = 1, sensor = 3, label = 13
Codes;
P0544 - Exhaust Gas Temperature Sensor Circuit - Bank 1 Sensor 1
P0545 - Exhaust Gas Temperature Sensor Circuit Low - Bank 1 Sensor 1

I have witnessed several different regen programming parameters with the 6.7. One was in a MY2011 March 2010 build truck, my job 2 December 2010 built - 2011 was slightly different and then it had the Nox sensor recall/reflash where it changed yet again, and now my 2015 behaves differently than the previous trucks and I believe more like the recently reflash for the previous model years...
So is it related to that specific failure? Was it because the old way wasn't EPA compliant? Was it because this is a better way? Who knows. Only the Ford engineer(s) that have made the changes know those answers for real.
On this board we are waiting to see if someone with a 2015 or a re flashed truck has the "stop safely now" EGT issue or not.
