My first tow with a diesel (2012 F350 47K Miles) was pulling a new 32' fifth wheel and utility trailer (RZR) I guessing the total weight to be around 14-14.5K. It pulled really well until I got 200 miles from home and then all of the sudden it just died. The message said something like stop now pull over safely (Friday afternoon 2PM).


After getting towed we ended up staying the night in the back lot of a small town auto shop. The problem? Exhaust temperature sensor (1of 4).
Luckily they had a truck from Salt Lake coming through at 6 am the next morning (Saturday) who was able to deliver the sensor. I was back on my way by 10AM.

 

That sucks Jeff.

Some guys have had multiple failures and are carrying a spare sensor, kpers DTC list, OBDII scanner and a wrench. You know what they say, if you have it you will never need it.... thats why I carry a defibrillator in my truck

Some info here

What model toy hauler are you pulling?

 

Thats weird, this mechanic says it always the 4th sensor that will shut the truck down. The 1st sensor on yours shut you down??

 

290 Montana Mountaineer. It's actually not a toy hauler. I was pulling double trailers.

It actually was the forth sensor. It was reading 25 degrees higher that the other three.

 

Thanks for the link. I will definitely carry two of these going forward.

 

Sorry to hear about your truck, glad to hear that they got you back on the road quick! I might start carrying Prostate Examiners gloves then

 

On my 6.4 I never had a sensor failure. Are these the same sensors? I thought I read somewhere they are using the same ones. If so they we should be over this failure rate.

 

The sensors are the same for the 6.4 and the 6.7s. I bought a couple of sensors last year before my vacation trip for the 6.4 and asked the dealer when I bought my 6.7 and was told they are in fact the same sensor. This is the sensor that shut down my 6.4L ambulance with a very sick cardiac patient in the back. We had to wait nearly 20 minutes to get another med unit to us to transfer the patient! Totally ridiculous as it could have cost this man his life for a $45 part! The truck did like all the others, gave a warning and then shut down as I was pulling off the roadway. This is a Ford problem! None of our Freightliners have had a failure and we are now into the 170k mileage range on a few of them. There should be a programming "checks and balances" with those sensors. If most of the time it is the rear one, you would know then that the trouble then is in the DPF, and should not shut the truck down. I realize that this sensor probably gets hotter than the others and probably why it fails as often as it does, but they should be better quality sensors in the first place.

One of the techs at my dealer said I should consider taking all of the sensors out and putting anti-seize compound on them and re-installing them. I'm not so sure about that idea yet. Still doing some research on that one!

 

If you watch 2ndStroke's video I would think that is a very good idea.
If you break it off then the pipe has to come off and drill and tap (12x1.25 LOL)

Thanks

 

Anti sieze is the only way to go.

 

on this subject..for the 6.4 there is a jumper wire off the passenger battery that you can use for a restart...so you don't have to wait.

Have not found if you can bypass on the 6.7. I hear it is possible. Anyone know?

 

Emergency vehicles should have none of this crap. Nor should any of us. For the time being, entities purchasing Fords for emergency vehicles should be put on notice that this failure is reasonably foreseeable and there for negligent. Before all the Forditarians start howling, let it be known I would show the same tough love to Chevy or Dodge or any other. It is how you force improvements.

 

I haven't heard of one yet Scott, but I will ask the guys that told me about the 6.4 when I see them again.
