EGT Sensor Failure

My truck had to be towed to the shop today. The wife and I were stranded for 2 hours and to say I was upset is a understatement. My truck has 13,800 miles and this type of failure is unacceptable. Is it necessary to carry extra sensors around in order to get your truck off the side of the road? BTW, my truck didn't even make it to the side of the road, we had to push it to a narrow shoulder on a busy side road.

Not sure if it will help but you, and anyone else that has had the truck shut down on them because of these sensors, should fill out a complaint online with the National Highway Safety Admin https://www-odi.nhtsa.dot.gov/ivoq/

Maybe with enough complaints we can get a recall before some gets hurt or worse.

I can see some person getting into pretty serious trouble in the right situation. I love the truck but reliability is the most important factor I considered prior to the purchase. Ford's track record in the Diesel market has been less than desirable so I felt they had to hit a home run on this one. I hope I made the right decision, Ford Motor Company can fix this minor issue. The question is, will they?

My 2008, which uses the same tech minus the DEF never had a sensor failure. I never carried a spare either.

that is what some are doing now. Get a spare. If you can remove all the existing ones and put anti seize there and put them back in.

Not the best to change one on the side of the road but it may be the best option if far away.

I agree that anyone who has had a sensor fail and leave the truck in an unsafe place should file a complaint with the NTSB. I had a sensor fail leaving my truck with 19,000miles in a busy intersection. Ford did not even program a limp mode to allow a move to safety. I am not even really upset that the sensor failed, more about how Ford would rather leave you stranded in an unsafe situation than possibly pay for a melted DPF. Is it going to take someone getting killed on a rail crossing with kids in the truck before Ford is forced to fix this? If enough people that have this happen file complaints the NTSB can force a recall.

A spare sensor will be in my inventory along with a 12 MM wrench shortly. I used to have a 1976 Shovelhead. I always carried a couple tools with me and a couple master links to get me off the side of the road, it worked too. I got rid of it though because there were better designed vehicles available.

What happens if you carry just one spare sensor and two decide to go bad at the same time ?.

So the sensors for the EPA stuff, how many different ones are there that you guys would carry a spare for? Is the EGT a different sensor and is it the only one that will shut you down if it goes bad?

I have a Brand new 2014 Platinum (234 miles) and am heading cross country the first of the year. I would like to know the sensors you guys bought and keep in the rig. Part numbers would be awesome!

Thanks guys.

I will post the part numbers replaced when I pick up my truck. I really hope this is an isolated incident and never experience it again. I will purchase the spare sensor in case it happens again but if this issue continues, Ford needs to do something.

on the 6.4 there was a jumper wire on the passenger battery that you could jump it and bypass the shutdown.

I'll bet you could fool one of those sensor into the same scenario that will allow the restart.

After some research, looks like your going to need to get a code reader to be able to tell which one goes bad, then have a diagram in the glove box showing location of each that will be code dependent.
