Ford 6.7L Power Stroke Diesel :: 2012 F350 - DTC P1249 Intermittently?
Mar 22, 2016
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?

My 2011 F250 6.7 started throwing multiple codes a couple of weeks ago. I cleared them but they all came back at the same time. What these are pointing to? I'm assuming they're all related?
P0402 Exhaust gas flow excessive detection
P1249 Wastegate control valve performance
P0471 Exhaust pressure sensor A circuit range/performance
It throws 9 codes total, the three listed above, 3 times each.

Currently truck is in the shop after having multiple episodes where it lost power. It has 47,000 miles on it. When pushing down gas pedal, just does not want to go. Very slow to shift through the gears and get to highway speed. Turbo was not there, and there was also a hard shift/jerking from 2nd - 3rd. Did notice the traction control sensor kick on a couple of times....which was just replaced since a hole rubbed through the wiring. (took it to Ford twice before they found the problem)
They told me today that the code generator said to look at wiring but they did not find anything (heard that before) and that the fuel is possibly contaminated with DEF. If that is the case, someone is messing with my truck! What I don't understand that if the DEF does turn out to be in the fuel tank, wouldn't we have the problem continuously and not intermittently over a month after driving thousands of miles and going through numerous tanks of fuel? We drive and average of 60 miles per day just for work, half interstate/city.

I have a 2015 F350, sometimes the info center will show what gear I am in and sometimes it won't. Why or what I can do so it shows all the time?

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

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.

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.

Searched with no results. What is the correct bolt torque for transmission pan bolts on a 2012 F350 6.7L?

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.

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.....

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.

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 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!

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.

I disconnected the red wastegate hose in order to address a low boost high EGT issue. This seemed to fix the boost / EGT issue for the most part, but now I get this P1249 code. The first time I got it I saw boost at about 20 PSI. I figured I would try to keep the boost below 20 in an attempt to prevent the code.
I managed to capture some log info when throwing the code. The highest boost reading I saw was 19.58. Pretty close to twenty but I question if I even should be getting this code at this level of boost?
Here's a chart with the boost info. Yes I still have a very bouncy EBP and hope to track that down at some point as well....

It only happens on a very Rare occasion.
When Cold, and when I start out as I open the throttle, it suddenly sounds like there is not a piece of quieting stuff on the engine. I mean its like I can hear right into the engine itself.
I back off, It goes away then I dont hear it again for another Month or two.

2002 F350 7.3 intermittently wont start after I've shut it off, it runs fine but sometimes won't start when it's (warm)? Wait hour or more and it starts right up.
Is there something I can look for before I bring it to a mechanic?
Just to clarify I am a gal with little wrenching skills but I can look at videos and follow directions if it's not too involved.
