Ford 6.7L Power Stroke Diesel :: 2012 F350 - DEF Error Messages / Shutter And Knocking Noise
Apr 28, 2013
Just bought a 2012 F350 6.7 4x4 in the beginning of March. After about 500 miles the "Exhaust Fluid System Fault - In 50 miles, speed limited to 50 mph" message displayed. So first thing that occurred to me was maybe it was low on DEF, so I added approximate 1.5 gallons as it had some already in there. I also called the dealer who said "well it just needs to be driven on the highway" hmmm, that sounded weird but I did it anyways. After that I started the truck and the message was gone. I thought that fixed it. - Nope, at about 1480 miles I got the same error message again.
So after getting the message again I just kept driving and the message went away. I thought ok. Yeah right! Now in the past few weeks I have been noticing that the truck almost wants to stall and begins to shudder when going over a slight incline and shifting from 5th to 6th at about 45mph. When I accelerate it makes a knocking noise. If I let off the accelerator, let it slow down, it downshifts into 5th and I then accelerate and it goes away.
And today... I decided to go for a nice ride. After about 10 minutes of driving I get the ole "Exhaust Fluid System Fault" error again. Crap! Again, I keep driving and after another 15min - I get that shutter and knocking noise. Anyway I drove until the the truck displayed "Speed limited to 50mph on next restart. I just kept driving and the error message mysteriously disappeared again.

My dad has a 2012 6.7 powerstroke with about 84,000 kms on it. Truck runs great, works great, but has a noise that sounds like its coming from a pump of some sort on the engine. I know nothing about these trucks and told him I would see what I could find out before we take it to the dealer to see if its a warranty issue. Video below.....

Just over 7000 miles all of a sudden I got this loud grinding noise in the rear end like a brake locked up. Pulled into a parking lot. Don't think it's brakes. Put the truck in reverse it got even louder for a second then it quieted down after that. Naturally this happened on a Saturday.

Is there a way to reset the CEL on a 2012 F350? I've tried unhooking the battery, but that didn't work. I know exactly what it is, one morning I was running late for work. And forgot to unplug my heater core plug. I know, I know, Just forgot about it when I was in a hurry. I just don't wanna pay the Ford house to reset it.

The truck (2012 f350 6.7 lb cc 131,600 miles) started fine. Then while i was setting up the defrost i accidentally hit the ac button. Well I then hit it again to turn off. At that point the engine stalled. Which has never happened to me before. I started it back up which took a bit longer to get it to fire. It now says "Reduced engine power" and runs kinda rough. I thought well im at the end of my fuel filters life so why not change it since i had one. Well the. The FF housing broke. After replacement FF housing and filter it will no longer start. I took the filter back off and checked to see if it was cross threaded or sucking air. I checked that twice. Still no start cranks fast and strong. Codes are
P2138 something to do with the gas pedal
P0193 fuel rail sensor A high
P06A6 voltage on circuit A is whacky (paraphrasing here)
P0532 ac pressure sensor low

2002 F350 single wheel 4x4, 280k miles chipped with a 6
My problem first started when the bottom of my sending unit broke off in tank causing me to run out of fuel at 1/4 tank. I dropped tank and repaired. A week later I noticed fuel dampness on my tank and discovered I crossthreaded cap on sending unit. About this time I started getting a shutter at slight acceleration only and a harder hit at idle. I thought air in lines so I dropped tank and reassembled. No air in line at all now but I still have a shutter so I replaced fuel filter in case of obstruction. No luck. Now since I have owned truck it has been a pain to crank in cold weather if it wasn't plugged in over night. It has been hard lately even in moderate weather since shutter started so I replaced both batteries today.
I replaced the ICP today also because I noticed the other day when there was oil on and around harness to it and when I unplugged it today the truck changed idle and there was oil inside. After I changed it I took it out and it still had the shutter and sound of a miss. At about 8 miles in it just died going down the road. I coasted to the side and it cranked right back up and drove home. The shutter doesn't fill as bad but there. Also I live in the mountains and on my way home after cutoff I had chip in Stock position and had to put peddle to the floor to climb hill. I've never had to do that. I'm getting worried I work for a living and caint keep throwing money at it aimlessly. I'm thinking at this point IPR or CPS. But I'm no mechanic so I could be completely wrong.

I own a 08 F350 which has 4:10 gears. After this last trip to AZ pulling 5th wheel and only getting 7 - 8.5 mpg driving 65 most of the trip, I'm seriously considering a new F350. Switch from 2008 to 2012 with about the same truck? I'm thinking of going back to 3:73 which I know works a bit. But if someone did switch what was your mileage difference. I have been also tossing idea of replacing my 4:10 with 3:73 to improve mileage. My 08 only has 24k on the clock.

I have a 2012 f350 srw that I'm trying to rectify an intermittent p1249 dtc. What I found initially was a broken vacuum line from the egr solenoid valve to the activator. This made the truck run good and the dtc code cleared. It came back two weeks later, the truck did not go into the reduced power mode. I pulled the MAP sensor to test it and it was completely plugged with soot.
I replaced the MAP sensor and removed the upper intake, cleaned out the soot, which was considerable, vacuumed out the lower manifold cleared the code. It went without a cel for about 1000 miles and came back. My questions are: where to go next and if the soot is normal for a 116K engine would I be better served by deleting the egr/dpf/def?

This past Monday I was finally able to pick up a 2012 F350 dually and over the weekend I was able to do an EGR and DPF delete and I come to find out while under the truck that it has an oil leak I looked under the hood and it seems that there is oil around the turbo and after the test drive there is a LightStream of oil coming down the exhaust.
Another question is that I have read about the possible problem is that early build 2011's have that's why I chose to look for a 2012 so I didn't even consider looking at the build date when getting it and I come to find out it was November 2011 and this truck has a plastic oil pan should I be worried about The possibility of this engine taking a dump on me and if so what can I do to prevent it?

I am new to the FTE world but not to diesels my 2012 f350 is my second diesel and a couple weeks ago I got home from work and fell asleep and forgot to plug in my pickup and it gelled up (was about 15degrees when I fell asleep and -20 when I woke up) so all the filters were replaced and everything was good after that for about a week, then my fass platinum pump started blowing the 30a fuse every 10 seconds and The pump itself smelled burnt so I replaced it with the same style and size of pump and the pump is good now but the truck is a no start it has thrown codes p2291, p0089, p0091, and p228e. It has 4inch straight exhaust, fully deleted (def and egr), h&s tuned, fass platinum 125 lift pump.

I have a 2012 ford f350 SRW 4x4 with the 6.7L. Problem I have just started to have. When going downhill in tow haul the truck at first will hold you back then all of a sudden it starts to up shift at 20 mph it reaches 6th gear pretty quick. I talked to the dealer and they suggested I was pushing the shift buttons, but I am not. They told me to drive it till next week and then they will see if there are any codes in it.

My Father In-law has a 2012 f-350 Dually with 4K miles. He tows a 9K lb camper and until our last trip the truck ram flawlessly. On our return from Myrtle Beach to central NC we were on a freeway traveling at 63 MPH and his tranny would not shift into 6th gear. Tow haul was on. There was some headwind (10MPH) but no large grades or any reason we can think of not to allow an up shift. His display did show a countdown to empty of the exhaust fluid 450 miles to empty.
He took the truck in for service and no codes were found. Dealer did not find any TSB's addressing the tranny issues. Is the sixth gear up shift in tow haul set very conservative? Does it hold 5th unless the load is below a certain value? Other trips we have been on have been mountain towing so 6th gear shift would have been on down hill or level sections. Dealer wants us to bring it to them when it won't up shift next time but dealer is not along a freeway.

1st Ford was an '08 to '10 model F250 6.4L that had an engine fire on I-82 towards Ellensburg in the passing lane.
2nd Ford was a 2005 F-250 6.0L at Vantage, he had black smoke coming out of the exhaust and a terrible engine knock, and was pulling a 32 ft TT. When I went to go talk to him, he had no idea what a ScanGauge was or anything about the truck.
When I looked at the engine bay with him I saw the EGR valve had been deleted with a block off plate and not plugged into the fan hanging on the side anywhere, he had the high rise aftermarket oil cap installed, ALL the metal/aluminum parts had bad oxidization. He had no gauges whatsoever.
Then to top it off, he said he was going to try and make it to Ellensburg while pulling his trailer. I told him he had a 4% grade for 10 miles in front of him to climb, and the another 35 miles after that on flat ground. All I could feel was, "is there any hope for this guy"?
Anyways, my question is, without any gauges, what would be some good educated guesses with the black smoke and knock? I am mostly just curious what this guys issue might of been with his truck since seeing the symptoms first hand.
My thoughts are the oil cooler leaking, and making the injector(s) stick open.
Of course now that I think of it, there's probably too many scenarios to mention.

I have a 2012 Ford F250 6.7 powerstroke. Truck has about 30,000 miles. Has been completely flawless and has exceeded all expectations. Well....I am experiencing my first hiccup.
I traveled yesterday. While going up a slight grade, running about 50 mph, 1000 RPM, 10PSI boost...truck started bucking and sputtering with weird sound coming from around the air box. It felt just like you had a blow out on the front right tire. My initial thought was i just had a blow out as the truck hopping. Well, once i let off the throttle everything went back to normal. It did this about 5-6 more times on the trip. When it would start doing this I would just let off the throttle and everything would go back to normal.
I've read a good a bit on this 6.7 and appears that turbo issues are common. Being optimistic, I am hoping this is something that can be fixed easily. Again, have had ZERO problems with this truck, runs great, and even now on the trip runs fine but now we have this intermittent issue that I do not like. I am very diligent in taking care of my equipment, have not abused this truck and all maintenance is current (actually a bit over kill). What the issue could be.

2012 F-350 King Ranch Diesel. I am eventually going to purchase a camping trailer to pull with this rig. I am thinking of bypassing the radiator with my transmission coolant lines. I did this on another vehicle and it worked GREAT! That vehicle was a 2001 Isuzu Trooper with that crummy 4L30-E transmission. My trans temps stay round 170 to 175 on the freeway which is far better than the 190 to 200 range that GM says they will run. At any rate, 2011-2017 F-250 to F-350 applications? I was thinking of adding a filter or two with a fan-cooler from B & M Racing Equipment.

My 2012 F350 Lariat has 6100 miles on it now and on the way home tonight I got a "speed limited to 50 mph in 50 miles" message on the display. It states that there is a "diesel exhaust fluid system fault". The def was topped off about 2000 miles ago and the message center says that the fluid level is "ok". I am going to be on the phone with the dealer first thing in the morning. This is my personal/work truck and if I can't tow a trailer then I can't work. My guess would be a faulty sensor. I have no doubts that the dealer will get this resolved quickly as they have been great about everything else. I also want to say that other than this, I am sure minor issue, this truck is awesome!

When the truck shifts into 5th gear i instantly feel a constant vibration and noise until it shifts to 6th gear. This happens nearly every time while driving at 40mph. Rpm range 1200 - 2000. I bought the truck new on June 30th and noticed the problem on my way to work on Monday July 2nd. Took it to the dealer on July 5th and the tech said it was the torque converter slipping. I drove it home because they didn't have time to work on it. Took it back on July 12th and the dealer has had it since (currently 30 days) They originally told me it was not the engine or transmission and it was an exhaust problem. Last week they said it was the motor mounts and said they would be done.

2011 F350 diesel with 10,000 miles. I have been experiencing problems with the truck loosing power, making rough running noise (pinging like an older diesel), and vibrating. As though the motor is bogging down. It usually occurs on small inclines or hills with the truck in higher gears and low rpms. It will also occur running on flat ground 65-70 mph. Had it occur once while turning the truck around in 1st gear and low rpms. Depressing the accelerator will bring the truck out of it.
This problem occurs randomly sometimes a couple of times a week to not at all. Took to dealer and they found no codes and of couse it didn't do it on the hour long test drive I took the mechanic on. However they did say they had two other owners come in with the same complaints, but could not get trucks to repeat the issue. Problem usually occurs in the hotter part of the day, maybe just coincidence. I had seen similar posts with this problem but no conclusions.

I've got a 2011 F350 Lariat crew cab and when i get up to 75 mph with a cross wind, there is a whistling noise. it sounds like a turbulent whistle as if its blowing across the ribbed portion down by the wipers. I tried to get audio but for some reason my phone wont pick up the noise, but its extremely loud at times. Sometimes it will wake up the kids if they're napping in the back seat.
