I know that's a normal msg, but what has me thinking is the fact I've had my truck just over 2 weeks and it only has 1350 miles on it. My understanding is that a tank of DEF should last at least 5000 miles (service interval), which means either my delivery prep guys overlooked filling it or it using way more DEF than it should.
View 14 RepliesI got the low DEF fluid message today. 800km to empty (500 miles). I checked early in the day and message said DEF fluid level was O.K. I never got the message exhaust fluid 1/2 full. I had a jug at home so when I arrived home I filled the tank. I had a 2.5 gallon jug. I assumed it would take the entire jug. It would only take 2/3. It would appear I have a false low DEF message. This happened shortly after purchasing the truck but then it seemed to correct itself until now. I now have 40,000 km's (25,000 miles) on the truck.
View 14 RepliesNew to Diesel trucks, have a 2012 F250 with 4000 miles on it. for the first 3000 miles I would see regular messages about "Cleaning Exhaust Filter" about every 100 miles or so, but this last 1000 miles I have not seen any?? I drive about 100 + miles a day, 55 to 65 mph so I'm sure I'm running it long enough.
The other thing I've noticed is that my MPG has gone from 17 down to 14 which is what I would normally see during a cleaning cycle. It almost seems like I'm in a constant state of cleaning as my MPG has taken a dive... Any things I should check?
Side note, I towed a 30ft RV around the 3000 mile mark, since the tow I haven't seen the message.
Well, last night I took my F-350 up a wheeling trail. I'd been up quite a few times in my old Rover, so I knew I could go a ways in without damage. Just uphill, muddy, and ruts / rock steps.
One thing I notice is that when you engage low range in the diesel, the transmission starts in 2nd gear. My previous gas Super Duties always started in 1st. I'm assuming this is to protect the transfer case from torque overload. Also, the throttle response seems to change when low is engaged (the pedal becomes less responsive, which is nice).
I've had the gas Super Duties off road before, and all of mine have had the locking rear diff. The diesel lugged along perfectly. My biggest fear was crunching the DPF / SCR / DOC canister on a rock step. In that respect, I'd rather wheel a gas. The manual shift function makes a lot of sense in low range - you can force a start in 1st, 2nd, or 3rd. And prevent meaningless up / down shifts since the grade can change quickly.
These trucks' biggest hindrance is their size. However, if you have the trail room, they are actually excellent off road. Many people look at a Super Duty and see a vehicle good only for pulling or hauling. Not so, these trucks are as good as a Jeep off road, again with trail room being the only concern. The locking rear diff was never really needed, but I engaged and disengaged a few times to keep the mechanism free. I really love this feature.
One thing that happens frequently for me in north-east wheeling is water crossings. Could be a simple brook but mostly it is mud holes encountered on tight trails. In some cases these are only a foot or so deep; in other cases they are 4 feet deep. Ford states to "try" to keep the water below the level of the hubs, which amounts to about 15". Aside from possible front axle contamination, my biggest concern would be the electronics on the diesel which are mounted to the frame or floor pan (transmission module, NOx module, etc.) The gas Super Duties don't have these concerns. In the old days, as long as a diesel had air, the engine would run under water. This engine requires electronic control of many things, including the injectors...so it won't. There are also some axle / transmission breathers which run about floor pan high to be concerned about, but these can be easily extended.
Maybe it's due to the twisty frame which GM loves to insult Ford about, but these trucks have excellent wheel articulation. I'd be surprised if a coil sprung power wagon flexed more, at least in the rear. I'm impressed.
Finally, the traction control. I experimented a bit on a slippery rock step. This was the only step which required the rear locker - sort of. The front wheels climbed the step, but the back flexed to the point of one rear wheel basically almost off the ground and severely unloaded. With 4x4 Low engaged, and traction control "off" as much as Ford will allow, the truck could not pull itself up. Turning traction control on allowed the truck to very nearly pull itself up. A little more throttle / finesse probably would have gotten the truck over, but lots of ETC operation glazes the brakes and spews brake dust everywhere. Being able to start in a higher gear manually really adjusts the torque control. Locking the rear end and the loaded wheel bit right in and she went up and over.
When doing some off-road driving, the "off-road" screen for those of you with the LCD message center is kind of fun and informative to watch. It's nice to see how far your wheels are turned left or right when spinning in ruts or what crazy angle your truck is on. Howie Long could probably document the exact up / down / left / right slope angle a Super Duty needs to be on in order for the tailgate not to open. I never had an reason to open the tailgate while in these crazy angles, of course.
Overall, very impressed. It's not as good as my old Range Rover, but I would say more talented off road than ALL other Ford vehicles except the Raptor.
I just bought a 01 f250 and started to hear/feel thia ticking/rattling noise. I have read a couple forums on the matter but I'm not really sure on what to replace ?

I have a po6a7 code boost gauge pegged at 40 code says vref circuit b out of range. What sensors run on circuit b and what could possibly be the problem my camshaft sensor is reading fault on scanner don't know if that has anything to do with it taking the truck to the dealer is not and option it's a 2011 6.7 with 75,000 miles....
View 1 RepliesI keep getting a problem code of P0404 - EGR Circuit Range/Performance. What it is and if its a serious issue?
View 2 RepliesI know that average normal tranny temps for the new 6.7s are 200 degrees give or take which my truck does as well. but I'm wondering about how long is normal for the tranny temp to get up to that normal range? My truck can take anywhere from 20 minutes to almost an hour depending on if I'm on highway vs lower speed driving and it's been that way since I bought it. Am I worrying over nothing or my worries not just worries?
View 7 RepliesI was updating the firmware on my mini max tuner today and decided to calibrate for the 37" tires. After calibration was done I got the code P1635, which is "Tire/Axle Out of Acceptable Range". Should I bring it back down to 34" where the FORD ECU stops calibrating? I mite have lost traction control with this calibration as well. Mite find out tomorrow if I get an itchy foot. Truck seemed to drive better and pull harder off the line....low rpm's.
View 14 RepliesI had CEL the other week scanned and found P2043 Reductant Temp/Sensor range. Light came on first thing after a cold start.
View 13 RepliesMy check engine light popped on for me a couple days ago. P2043-reductant temperature sensor range/performance. Truck still runs like a raped ape, no change in driveability. Just over 21k miles. No "speed limited to 55" messages or anything else. Basically no change in the truck other than the light.
View 12 RepliesI have a 2007 f-250 6.0 liter turbo diesel. I was pulling a trailer with a golf kart on it and was not in tow haul. I was going up a hill and it shot up into 5th gear. I pulled into my house and shut it off and refired it and it acted fine. I went on a little test drive to see if it was going to do it again before I went on my trip. As soon as it shifted into third gear the tow haul light started to flash on my dash and went to 5th gear and would not down shift even if I did it on the column.
I scanned the truck with my snap on modus and it gave me these codes. P0706-transmission range sensor A circuit range/performance, P0707-transmission range sensor A circuit low input, and P1702-transmission range sensor circuit intermittent. I put a transmission harness in it and started it up and it ran fine and the codes were gone. I went for a test drive around the neighborhood and as soon as it hit 3rd gear it did the same thing as before. Today I put the old one back in and checked the codes so I could write them down and there weren't any so I went for a drive and it shifted through all the gears great and downshifted fine as well.
I pulled into my drive way to check for codes once again and there weren't any. I was gonna go for a ride in tow haul to see if it would do it and as soon I put the truck in reverse it started to idle high and the tow haul light started to flash again. I put it in drive to pull back into my drive way and it immediately shifted into 5th gear and threw the same codes...
My truck gave me the message that "DEF under 1/2 full", so since we are on the road, I stopped by a dealer and picked up 5 gallons of motorcraft DEF. I did not want to get the countdown message in an unfamiliar area and have to look for it. While going out site-seeing, I forgot and left it in the back seat of the truck for about 8 hours in the heat of the day. I know you are supposed to store it under 86 degrees or so. Now, did I just ruin 5 unopened gallons or is it still safe to use?
View 9 RepliesI have seen this pop up on the truck I think 3 times now over the first 4000 miles on the truck.
Usually it's when I'm on the highway around 70mph or so.
It comes on for a few seconds, then goes away. I do have an exhaust / tune on the car.
Got my first CEL at just under 40K miles. P4023, Redundant temp sensor range, so looks like I get a new DEF tank sensor. Of course they are on national back-order still. One would have thought that Ford would finally have these in stock but no.....
View 8 RepliesI haven't had any issues with this truck before but last night I pulled out onto the highway and my check engine light came on and a message saying engine power reduced I finally got it to reset after 4 times of shutting the truck off, was wondering what this may be without knowing the code. I tried plugging my edge cts into it from my 6.0 but it wouldn't communicate guess it needs a update trucks a 15 f350 with only 30000km.....
View 2 RepliesMy low fuel light came on tonight. I drove about 2 miles, stopped and shut the truck off. When I restarted it and began to drive off to the fuel station a notice came on that isaid power reduced then a check engine light came on. I was about a mile or less from the fuel station so I filled up. I cycled the key but the engine light is still on. No low power message tho. The power is fine.
I came home and drained the water drain on the filter, didn't see any water but hoped it would solve the problem. I cycled the key a few times and started the truck but the light is still on. My truck is a 2013 f350 6.7 and has 211500 ish miles on it. I bought it a month ago with 18500 miles and haven't had any issue until tonight. My only thought is maybe the fuel filters need changed. I don't know if or when the previous owner changed them.
So I just went on a vacation pulling my horse trailer (first time leaving the state with this truck) and at about 5 hrs into the trip I had a message Reduced Engine Power and went from 70 on the interstate to 10 miles an hour and slowing rather quickly. I ended up shutting it off and restarting and it came back just like normal. I found the nearest ford dealer and they put the computer on it and it showed absolutely nothing, no codes and nothing wrong. The mechanic reset some things and we went on our way.
Then I ended up getting a check engine light saturday. I found someone to read the code and it came up with P164A which is an O2 sensor, he was able to clear it and I put on probably 50 miles today and no check engine light. I have about a 10 hour drive back home. Still debating if I take it to ford near here if they will do anything now that it doesn't show a light?? I hate to chance getting broke down on the highway with a truck that will basically shut down like that?? It just doesn't make sense to me.
Got a Decreased Power message across the dash info center today and was limited to only around 5lbs boost. I stopped and pulled the codes and here is what I found:
P054E - Fuel Quantity lower than expected
P1249
P1247
P0471 - Exhaust pressure sensor range/performance
P02D7 - Injector learning @ max
P0402 - EGR flow excessive detected
I dumped the trailer and limped home to change the fuel filters. I could only go 35mph on the flats and 10mph on any kind of up hill slope. I switched out the filters, purged the air, fired her up and cleared the codes, all seemed well. I backed out and went for a test lap around the neighborhood, as soon as I turned the corner and rolled on the throttle and reached 35 the message came back and the codes returned. I will be towing it in to the dealer tomorrow for diagnostics.
I have a 2011 Ford F250 6.7 Powerstroke. It has 107,000 miles on it.
The other day I was driving it down the highway and it got a Reduced Engine Power message on the dash. It lost power and I got off the highway to the service road. Then it died on me.
Had to get it pushed to a station then towed home. It wouldn't start. The starter cranks over for a few seconds but engine won't start. Checked all the fluid levels and batteries. My DEF fluid was only a half gallon low.
What I have noticed is that the DEF level indicator hasn't reminded me that it was low for over 4-5 months now. I had been putting in about 2-3 gallons every 3 months or so. But it hasn't reminded me lately and I just forgot. This is my first diesel.
2015 F350 6.7L, 43,000miles
My family and I were driving into West Virginia this morning when the reduced engine power message came up on the dash and the truck died. I coasted off to the side of the road as best I could and got out. Immediately I smell diesel fuel. I look under the truck and there is fuel all over the passengers side frame and when I keyed it back up fuel started spraying down by the right front wheel.
Pulled the fender liner back and saw a small rubber hose that looks like it came off of a tee fitting down by the egr components. I tried to get it back on but wasn't able to get it seated 100% and when I tried to restart it blew off again. Truck is completely stock and ran perfect right up until it died.
