Ford 6.7L Power Stroke Diesel :: Engine Shut Down Descending A Steep Grade
Jun 27, 2015
I do not think, I have seen anything about the engine shutting down descending a steep grade. first it threw the "wrench" warning and than that the engine was going on limp mode. luckily no one was on the road with me, coming or going. i pulled off on the shoulder with part of the pickup and 5er on the road. no steering or brakes used the 5er brakes to stop. turned the key off and restarted it again and no code or warnings. like nothing happened. it happened twice today between yellowstone park and great falls, mt. the second time the engine light stayed on and i had to stop and turn it off and restart it and it went away.

In addition to significantly louder noise from the Turbo on start-up, we've started to hear a pretty concerning noise while descending a hill in Tow-Haul. Not sure that the T/H has anything to do with it other than getting the engine in a RPM range that causes the noise. We've taken it in and tech says "That's just normal noise"... What ever that is.
Here is a link to an example : Tow haul making a lot of noise in my F350 diesel. Pulling a very heavy horse trailer. - YouTube
Best next steps for a 64,000 mile 2012?

Every time I climb a grade, I get the 299 code. My VGTs go to 15 or 85. Does this indicate my turbo is sticking?

What besides a 4" exhaust can I do to lower EGT? When I tow with my tow tune the EGT gets high on long steep pulls. Would like to be able to use it with the tune because there is more power and it pulls nicer, but I want to lower my EGT. I have a 4" flo pro system coming. What else can I do? Would a new intercooler make much of a difference? Already have an S&B cold intake and Banks Hi Ram.

The thing is the truck seems to run fine. But, when it hits 30 pounds of boost it goes in to limp mode. Good way to get yourself run over on a highway. I'm wondering if the computer or whatever has gotten off somehow and is sensing a problem too early ? Would a re-flash possibly correct this ? BTW, it is a 2005 with 63,000 miles.

I am working on a 2007 F350 ambulance for a volunteer fire department. It run great, even with the key turned off sometimes. This is an intermittent problem. About every 10 times it is used the engine will not shut off when you turn the key off. The instrument cluster turns on and off as normal. The other odd part is if you leave the key in the off position when the engine does not turn off the RPM starts going up. I have not left it in off long enough to see how high it would go. It does not have a remote start and never has.

My 6.7 makes a humming noise when i shut down my engine. Starts a little loud and gets softer at the end. it last maybe for a minute. But here's the catch if i stick the key back in the ignition it stops and as soon as i pull it out it starts again.

The EMS service in the county next to ours lost one of it's new trucks for a few days on Tuesday. While going on a call, the engine made a tapping sound for only a few seconds, then a loud pop and shut off. Ford dealer went and picked it up and took it in for evaluation. VERDICT: Broken rod and cracked block. I have to say, this is the first I've heard of a 6.7L having a problem like this in our area.
Ford was really interested in this engine, as a new one is already on the way and the old one is to be shipped back for complete breakdown. So far, the Director and County Manager have been impressed with Ford's response to this problem. Dealer has told them the truck should be ready by the middle to end of next week. If I hear anything else, I will let you know. Any engine can break at any time, I'm just glad they are moving quickly to rectify the situation.

Having that flash on the dash? Truck was running fine and the buzzer when off and dash said I think -- when safe stop and shut off engine immediately. Scared the scr-p out of me so not sure if that was word for word. Jump on the binders and got it off the road and called a wrecker. Now it's at the dealer waiting for them in the morning. Checked oil and don't see any leaks. Now I have lost my confidence in the truck. 42000 miles on it.

I have 2003 f250 7.3 automatic 181,000 miles completely stock. Never had chip,tuner or anything on it. I am second owner and got it when it had 70,000 miles on it. Ok here we go I live on top of a mountain and soon as i start up the mountain or any steep hill, or pull or tow something my service engine light pops on. First time it came on I took it to diesel shop they hooked it up to scanner and said it was code p1211 said icp sensor was bad so they put new one on. Couple days later light started popping back on so i decided to order a auto ingenuity after doing some research.
Hooked up to truck started up mountain while scanning at wot light pops on code p1211 and think it was live data I remember seeing icp pressure at 1922 and duty cycle at 63% i was trying to drive and read it at same time and my lap top went dead. What does this reading mean 1922 pressure/ at 63% cycle done little research but dont really understand. Year and half ago replaced all orings on all injectors, new rebuilt hpop pump. New ipr valve, glow plugs, past month 2 different icp sensor new,and new ipr valve new pig tails on both and light still popping on.

Not sure, it doesn't seem to me the dreaded fuel pump problem. Was driving on highway pulling my 5th wheel after going though the toll both it never went out of 3rd gear and motor started taping pretty bad, turned tow haul off and it shifted up. All along never seemed to lose power, as I was looking to pulled off high way and into A park in lot it started losing power then just shut off. All along this 2min ordeal the motor was knocking/taping. Seems to me like the motor blew.

Had an egr fault code but I'm at a loss.....

Last November I forgot to plug my truck in and it got down to 0, my girlfriend tried unsuccessfully to jump start it. When I got home I jumped it and got it running. I took it down to a heated shop to troubleshoot the glow plug circuit. I discovered it was not getting 12v to the glow plug relay. Also I started it and tried to back it up in the shop, when put in reverse it killed the engine, not lugged it down it was like you shut the switch off.
Also I discovered if you turn the lights on it kills the engine immediately. It will not crank with the lights on either. So far I have replaced the computer,ignition switch,batteries, and cam positioning sensor. Now comes the weird part!! I decided to get it running and pull the bulbs out of the back up lights I pulled the drivers bulb first then the passengers side bulb. When I pulled the passengers side bulb it killed the engine.
It is not my daily driver so it still sits in my shop. I have a hunch it's a ground issue but I've checked and cleaned up all the grounds I can find and it still has the problem.

I just got 500 miles to empty message. On my next trip out I grabbed a 2.5 gallon at my local auto parts store. When I had 99.9 percent of the jug in, it actually started to spit back out. I got the rest in and figured I was done. It did seem strange that it only took 2.5 as I figured it was just about empty to get this message and 2.5 would only take me half way. Anyways, a few trips later and the message is still there. Do I have a bad level sensor or was it spitting out prematurely? Shouldn't 2.5 gallons have killed the warning even if it didn't fill it?

I have a 2005 f350 6.0 and it has a startup kit installed. When I start by using the key works perfect. But won't shut off by key! I have to use the stop button on key fob to kill the engine. I'm thinking relay might be stuck? And the relay on start up kit is working? Key removed it doesn't diesel down, it runs like key is still in.

Just to give you a run down on my truck. It's a 06 F-350 4x4 supercrew 6.0 with 78,994 miles. The trucks has been studded with Apr and aftermarket head gasket, Powermax turbo with a wicked wheel, RCD EGR delete kit, 5" turbo back MBRP exhaust, Driven Deisel regulated fuel return system, high REV valve spring kit, EBT sensor, 58volt swamps diesel FICM, edge evolution, within the last 4000 miles New oil cooler, crank sensor, cam sensor, IPR valve, ICP, batteries and lift pump. I think I'm missing a couple things but that's the layout.
Now for my problems recently took the truck to Florida from Illinois towing a 8500# boat. Before I left I had the oil cooler changed, Rotella T6 5w40 ,New filters And 2 bottles of REVX. The try k didn't miss a beat on the 1300 miles trek down. It sat for 3 days before coming back up lite truck. I was gonna drive straight thru and with 1100 miles down and 200 to go the truck acted like it was running out of fuel and died at 90mph. Fuel Gage read 1/2 tank to go.
After letting it site a 1/2 hr it finally fired back up and drove 5 miles before doing it again. This went on 3 more times. I even limped it to fill up the tank thinking the gauge was bad. Nope did it again And called for a tow truck. This was in mid october and 20 miles ago. Since then I've replaced fuel filters, lift pump, IPR, ICP, cam and crank sensors, sent the FICM in to have tested, replaced batteries. No the problem is worse. It Now has created a serious miss when it's cold till 90 then it Idles smooth but keeps dying on me like it did when it was towed.

I am award of the problem. And hope to be one of the majority that never has to deal with the issue. But, if the problem were to happen and the code thrown could it be as easy as to pull over. And if you had a code reader that could clear code.
Could you simply clear the code and be on your way? If so, how far would you get before the code reappeared and you had to repeat the read and clear the code again.

So today I was driving down the highway and my engine shut off. No sputter or any thing I had just filled the tank. I tried to start it and it wouldn't start. It's been hitting a dead spot at around 3000 rpm like its not getting enough fuel or something. Right now I'm thinking it's an ipr valve but would like to know if what was the cause and how did you fix it...

My 2011 6.7 just started making a hum noise after shutdown. I've read that it might be the wastegate solenoid. Is there a TSB for this. My truck is tuned so hopefully my dealer will be tuner friendly.

2003 6.0. Really, really hard or no start in winter. Started it up today and it misses until warmed up. That sounds like injectors.
The next issue is it stalls randomly they say. I tested FICM with a volt meter and it's constantly just a hair above 48 volts. Key on, cranking, running, doesn't matter. It's a 7 screw FICM in an 03 so I'm guessing it's been replaced. It also has 3 zip ties around the back half of the FICM. I'm not sure if it's holding the FICM in place, or holding a connector on the back.
Today after testing the FICM and starting it, and getting it warmed up, we let it idle around 30 minutes. It stalled like the key was shut off. When this happened, it would not restart for about 1 hour. It would crank and spin over fine, but you could tell it was just the engine spinning over and the injectors were not trying to fire. When it finally did start an hour later, it took some cranking and you could hear it trying to fire like the HPOP was empty and building up pressure before it lit off.
No CEL and oil pressure gauge on dash moved up to the middle while cranking. I'll put the scanner on it next time I'm there and watch live data during the no start condition. What all to monitor while cranking or where to look in case this isn't an unheard of 6.0 issue.
