Ford 6.7L Power Stroke Diesel :: 2012 F350 - Tow Haul Mode Upshift
Jan 30, 2014
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.

Is there a way to auto engage the Tow/Haul mode when you plug in a trailer that requires brakes? Be nice since I sometimes forget to push the button after we stopped for lunch...

How do you diagnose a bad fan clutch? When driving in tow/haul mode I get a noise like a jet engine. It starts going down grade or upgrade and does not stop after leveling out. I have switched off tow/haul and it is still there. Over on the Diesel Stop site I found a couple of guys who have had the same problem. Concern is everything I have read there are no codes thrown. Have not taken to my local Ford Dealer to see what they say.
Driving a 2011 F-250, August 2010 build date with 76,500 miles. Problem started about 6 weeks ago when pulling an 8000 lb travel trailer in the White Mountains of NH.

Quick observation: with the exhaust brake switch off, I notice it appears that the exhaust brake is still working automatically when you are in Tow/Haul mode and apply the brakes coming down a hill.
I notice the engine drone and turbo boost gauge rise...although neither the drone nor the boost are as noticeable as when the switch is turned on.
I know the 2011-2014 had "auto exhaust brake only" but it appears some of that functionality is still built in.
Another question: what is the consequence of turning the exhaust brake on and leaving it on for normal driving? Is mpg affected? Engine output? Engine wear?

It's on my 2015 f-250....dont know if this is a new thing ..... I know my 2011 f-350 didn't have it..... Really hardly notice its working ....it slightly slows me down when in tow/haul mode while braking......

Have a 2003 F350 srw 4x4, 107,000 miles on it. Driving it last night tow/haul light started flashing, hooked up AE got a P0730 Incorrect gear ratio. Truck seem to do ok, cut it off went back out a little while later and the tow/haul didn't flash.... Only issues I've had is when shifting from P to R, it takes a second or two longer than it should and shifts hard when it does but it doesn't do it every time.

Friday I pulled my steel gn 3 horse trailer about an hour each way. with the horses it weighs right at 7000 pounds. no issues. Saturday morning I drove to town, no issues. Saturday evening, I got in it to run down the road and about 2 miles from the house, the check engine light came on and the tow haul light started flashing and the temp gauge is dead. drives and shifts normal, tow haul button still functions. Truck is stock except for an EGR delete. No tuner, FICM was rebuilt. I had it on a battery minder before I left and was thinking about pulling the batteries and letting it sit for a while to see if it clears. Scan Gauge II shows no codes.
Sunday: So I let it sit all night, batteries connected and it was completely normal this morning. will see what happens when I drive it to work tomorrow
Later Sunday evening: So I just took it out for a test drive, went a couple miles down the road, shifting normal for a cold start. Temp gauge is working, just as I am almost back home. 5 miles at the most, temp is coming up to normal, gauge goes dead and check gauge light comes on and tow haul starts flashing. I think it might be the sensor.
This morning: I got about 6 or 7 miles from home, trans just got up to temp, pulling up a hill, it shifted out of overdrive, tft gauge went dead, check gauge light came on and the tow haul light started flashing. still shifts like it always has and the tow haul button still functions.
I am thinking it is just the temp sensor. Truck has 159k on it.

What the problem is with my F-350 6.0. I have an intermittent problem with my Speedo reading zero while I'm doing 70mph on the fwy. since the speedo won't work the truck goes into limp mode, the turbo will not function at optimum level. I have replaced the diff. sensor, the trani sensor, the a.b.s.sensors, the instrument cluster to a reman cluster. Then when I had a local mechanic plug a laptop dianostic program on it as he was running through the system inadvertently the radio cut out, so I found that who ever installed the after market stereo they cut a few wires to the harness, I went to the junk yard found the harness end and replaced the end. so with all that said and done no one knows what is causing this speedo not to work and limp mode. about 4 years ago the oil pump stopped working and ruined the turbo so the whole front end of that glorious 6.0 was rebuilt the problem started about a year after that.

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.

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?

Everything was fine, running PHP 200X tune, switched to PHP 65 tow and took the 5er toy hauler on vacation last month. Pulled a lot of mountains,etc. While camping, took the truck unloaded to get fuel. Engaged tow/haul going down a mountain to utilize engine braking and the tunes "exhaust brake" and the trans slammed HARD into first gear. This happened twice. I refrained from using tow/haul. Heading home 450 miles with the 5er, I utilized tow/haul again (had it on the whole time, just like on the way down) and the truck and trans were flawless. Get home, switch back to 200X, and I'd say within a week or so, began having trans issues. Loaded stock tune, reset KAM with SCT, disconnected batteries with headlight switch on for a couple days, reloaded 200X and drove it for a couple days. No change.
It felt like the trans was slipping, not "going" like it should when on the throttle, and would sometimes not want to upshift. It would just act "weird". This would usually occur under 40 - 70% throttle (I rarely ever get on it more than that), but sometimes less. Never got any check engine light or tow/haul flashing.
So today I finally did what I should have weeks ago, took off work and ran the truck to a shop.
- First the tech hooked it up to the scanner. No codes.
- Test drove it. He said it drove fine for him. It was fine for me as well, driving it from my house to the shop (I didn't "get on" the throttle though).
- He monitored the voltage from the trans temp sensor. He said the voltage was fine, didn't spike or do anything crazy. He didn't seem 100% positive on this but, said it starts out at 5V cold and voltage should drop as the temp increases, which it did. However, the temp started out at 300 and then dropped to 200 as he was driving. #1 the temp isn't (shouldn't be) that high, and #2 it should increase while driving not drop. The temp shown on my Torque Pro app hit 149 on the way to the shop and 168 on the way home (90 degrees outside). So he seemed to think there was something screwy there.
- While driving it, his scanner showed a trans overheat (over temp/high temp, whatever) code, but no check engine light or tow/haul flash.
- Drove it home. Trans was fine until I got on it a bit and then it acted funny again. But just driving normal with light throttle it is fine.
* Thinking about trying a new temp sensor.
* Could it be in limp mode which is why it feels like it is slipping, i.e. doesn't have the normal power I'm used to?
* When the tow/haul light flashes, is it the tow/haul light on the instrument cluster? That's the only thing that lights up when I'm in T/H. Where you push the button never lights up. Assumed it was just white lettering and not a light.

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.

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.

One of our trucks, 2004 F350 Powerstroke, my company truck, recently the last snow even we had, my tow haul mode would pop on and off almost evertime I shifted from drive to reverse while plowing. I didn't want it on, it just kept poping on and off. Thought maybe the button was stuck, but it moved like normal. My other thought was there is a loose connection in the shifter or column causing it to go on and off.

So driving the other day and tow haul starts flashing. I come to a stop sign and goto take off and it barley takes off. It will barley roll if my foot is off the pedal sometimes wont even roll. Also won't shift into 6th. Once it gets rolling though say till about 25 it's fine. Just doesn't wanna take off? I scanned the trans but got no codes. And here are some pressures and stuff but I don't know what I'm looking for with the trans. This was all done in park.

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.....
