Texas | I have just picked up my 2012 F-350 with the 6.7 litre diesel from the dealer for the second time in about 3 weeks. What's the problem? I'm glad you asked.
These trucks have 4 EGT sensors on the exhaust system that are failing between 50,000 and 70,000 miles. When they fail and they do without any warning whatsoever, you are dead in the water. The truck will start to shift down until you reach a creep speed and then shut off. You can't start it again without the Ford dealer overriding the system and clearing a code. Even so it will immediately happen again and again until the affected sensor is replaced. An aftermarket code reader will not clear the fault code. It was described to me by the mechanic yesterday as a hard code that only a Ford tech can clear. The sensors are about $60 apiece and the labor is about $300.
If you have 50,000+ miles on your truck, I highly reccommend that you make a beeline to the nearest Ford dealer and get it done. You will have to pay for it as the warranty doesn't cover the repair, but you will avoid getting left high and dry at a most unexpected location. You will save a tow bill too.
About three weeks ago at 10:30 pm my daughter was shut down on I-35 in Oklahoma while pulling a loaded trailer. She had to wait until we could get it towed off the highway. I'm just glad her cell phone had a connection so she could call for help. One sensor was replaced and the truck sent out the door.
Yesterday I was driving and pulled up to the fuel pump. Filled the truck, got in, started it up normally without any codes or warnings and put it in drive. The truck took off and immediately shut down. I had moved forward about 10 feet. Once again I had to call and have it towed to the nearest dealer. This time I told them to replace the remaining 3 sensors that hadn't been replaced. The service manager told me that they were seeing these trucks come in with a bad sensor between 50,000 - 70,000 miles. He has some customers that are now carrying extra sensors with them. I'm thinking it would be pretty hard to replace them on the side of the road somewhere, but I guess at least a Ford mechanic could be called and save a tow bill if you had an extra sensor with you.
Ford is likely to get a lawsuit over this once someone looses their life because of this failure and forced shutdown. It is very dangerous and cannot be overridden to "limp in". I like the truck and the engine, but I sure don't like the forced shutdown when a sensor fails without warning.
Remember, you have now been warned. I hope you take notice and don't get caught like myself and so many others. |

SC | Btdt. Stupid EPA emissions junk. Going back to gas pickups soon. Too much to go haywire on the new diesels |
|
| |
|
| Emission equipment is covered for 80,000 miles, federal law.......I think |
|
| |
|
North west MN | Ya until they get this emissions junk figured out on the New diesels YOU are better off with gas pickups unless you really need the extra pulling power. The new diesels remind me of the middles 70's with gas vehicle when they tried smog pumps and cat converters that didn't work |
|
| |
|
Texas | Better double check that warranty claim. Mine was not covered and it has less than 80,000 miles. Towing wasn't covered either. |
|
| |
|
| Probably no different then Dodge or Chevy. Probably do the same thing. New diesels are to restricted any more. Better keep my old 7.3 around awhile |
|
| |
|
| When were EGT sensors part of emissions? Never have been........ |
|
| |
|
ECMN | Wow I am surprised it wouldn't at least idle so you can stay warm. |
|
| |
|
North west MN | Plus one! Can't beat the old 7.3 |
|
| |
|
Elsmore, Kansas | I recently traded my 6.0 stroke for a new to me 6.2 gasser and as of now I couldn't be happier. I really miss the diesel when pulling which isn't to often but the rest of the time I am HAPPY, HAPPY, HAPPY! |

ND | I did the EGR/Urea delete on my '12 Duramax for these exact reasons. Had a few warranty issues with the emmisions system so I got rid of it. Whole new animal now. Sounds like a diesel and smells like a diesel now.

They are part of the emissions controls, they monitor the temperature of the exhaust for cleansing purposes. They never had them before, now they do. You don't need 4 for any reason other than emissions.
The shut down is a safety precaution. When the sensor fails and reads max temp it shuts the engine down to protect it because it thinks the EGT's are way too high. They will flash the message "Stop Safely Now" but it usually shuts off faster than you can stop.
If you let the computer reset for 30 minutes or an hour it will restart again and you will be on your way until it acts up again. You cannot cycle the key at all during this time.
Ford is having a lot of problems with these sensors. The shut down is aggravating but if the EGT's truely did get out of wack then that shut down may have saved your engine. |

Sourthern WI | I agree with all you said but, given the choice between smoking an engine and getting t-boned by a semi in the middle of an intersection when my truck shuts off, I'd rather replace an engine.
If it's true that the engines just shut off, that's VERY poor on the part of Ford. Derating? Just fine since it allows me to get out of harms way.
I know guys are all high on this new 6.7L, but I can't help but wonder about how reliable they will be once they get some age/miles on them. They are just so stinkin complicated and with more parts comes more probability of failures. |

south Texas , York Rife Freemason | Not just ford ,thank the EPA . |

| My egt sensor crapped out in the highway, left me.
Local hole in the wall dealer had it, so must be common.
Started getting a low fuel pressure warning, been using napa gold filters.
Threw the code yesterday as I was passing a dealer. Pulled in, no other codes.
Bought a set of ford filters, changed, but yet to see a difference.

Id be extremely worried right now. Those CP4 pumps are known for their failures especially on the 6.7. |

Not saying I agree with it, they should at least give you an override si you can get off the road.
There is always the potentisl fire risk though too.
In the end you can blame lawyers and the epa. |

arthur , ontario | they had a recall for ambulances, not that long ago? but said the average smuck is on his own? get used to sittin on the side of the road! |

Northeast Louisiana | Do I need to take you to Texas in my Duramax so you don't miss your hunt? |
|
| |
|
| Nope, thinking about taking the RAM. It gets 20 mpg, ford gets 13. Should be able to haul back some serious antler.
If i do, I'll buy me a couple denim shirts, some red man, long leather wallet, practice a little redneck twang, and some pointed toe work boots with chrome toes.

| Not good for Ford. They've had something like 4 diesel engines in about 10 years. The newest one is not proving to be any better. I like a Ford truck, but they just don't have that engine right. My good friend is highly placed in Ford. When I was shopping for a diesel 3/4 ton this year I asked him his thoughts, as going by Internet forums brings out the die-hards from all sides - I wanted facts.
He gave me this advice: Do not buy the Ford diesel. They are seeing a lot of problems with them that may take years to iron out, if ever. His advice: go to the Ram with the Cummins if going diesel. To me that was all I needed. This person sees everything come through - good and bad - with Ford (and the others!) and for him to say stay away was the final straw. If only Ford and Cummins had come together years ago......
I now own a new 2013 Ram 2500 Laramie Longhorn with the Cummins - very happy with it!

They can be used in emissions, but it is likely more along the lines of making all of that extra power everyone wants without burning up the turbos. For a long time, diesels were just tuned so that you couldn't possibly burn them up stock. When guys would hot-rod them, they would add EGT sensors so they didn't burn them up when they hauled something heavy. I suspect the newer ones have some of that hot rod tuning to give you some extra power when you need it, but back it off before it does damage.
I like my '03 5.9L, manual transmission, manual transfer case, 19MPG Dodge 2500 more and more every day. My only complaint is the thin sheet metal. When I'm gone many, many years from now, my kids can either fight over it, or figure out which scrap yard to take it to. I'm not getting rid of it. |

Agree, get a real Diesel engine. Ram with the Cummins. Just look at all of them on the road. |
