Ford 6.7L Power Stroke Diesel :: False DEF Fluid Message - 500 Miles To Empty
Sep 2, 2014
I 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.

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.

New 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.

I have a 2011 f-450 6.7 - truck has 70K miles. The other day I was driving and the message said "Cleaning exhaust filter ". I usually keep it running a little to finish. Then shorty after a warning message came on which said "800 Miles to Exhaust fluid empty". So I went to fill tank and it was FULL. Now the warning keeps showing up each time I start the engine. It now says 300 miles to empty. I'm afraid it's going to go into limp mode even though the exhaust fluid tank is full.

New 2015 KR. Has 2191 miles on it so far, 69 engine hours and 21 idle hours.
Truck is telling me exhaust fluid is under half full. I thought a full tank of it was supposed to last around 7k miles???

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!

Finally, you can get EGT's with the Torque app!
I had to reinstall Torque on my new phone and EGT1 was in the predefined set of PID's for Ford. Launch Torque, the go to Settings, Manage extra PIDs/Sensors, Menu, Add perdifined set, select "Ford (Incl PowerStroke)". I believe it's getting data from EGT11 that is between the turbo and the DOC.
I included a graph that shows the truck running empty at 50-55 MPH, ambient air temp. ~50F and the EGT's are around 430F, at 60-65. They are 480-500F. If one of guys/gals with the Edge Insight/H&S/other tuner would be kind enough to confirm those numbers are correct.
This was on a 2 lane highway following a couple of old rock haulers, then I passed 'em.

fuel gauge does what it wants? It goes down to half way then goes back to full or sometimes even empty. Not a big deal for me because I have gotten used to it. But I would hate to have my wife in here and she thinks it's good and run out.

The installation of the new 50 gal. Titan tank went well overall. Start up was smooth with no leaks but the fuel gauge is showing empty with about 45 gallons in the tank.
The sending unit was properly oriented ("clocked") so I'm guessing the electrical connector is not secure at the top of the sending unit. Not sure I can reach the connector without lowering the tank somewhat.

Should the upper fuel bowl be empty after sitting for 30 minutes?
I believe no. Which would indicate to me a stuck open injector which Iv been suspected of. Iv been trying to track down a miss that I have and Iv been suspicious of a bad injector but ain't been able to pinpoint which one yet.

My fuel gauge acted pretty weird today. When I left my house today it was just above half a tank. I was sitting in traffic quite a bit and then looked down and it was below the e. I knew it wasn't empty so I kept going. Got to work. Went for lunch and it said full drove about 5 mins to eat and it went down to half a tank. What's going on? I am thinking of the fuel sender or wiring?

I have 07 F350 6.0 never heard this out of any of my 6.0s. it's almost a whine but can hear it w turbo and out of empty exhaust. Almost like a supercharger noise stumped almost leaning towards actuator for turbo? Noise got real loud swapped turbos used same actuator noise is there but much quieter.

Fuel gauge goes back to empty when I fill the truck all the way up. It goes back to full once I have used up 2 gallons ( from 36 gal to 34 ) on my 2012 F350. I also had a similar issues years ago with my 2003 6.0L .....

While servicing the bosses 121k 6.0, I noticed the coolant resevoir empty. It took 1 1/2 gallons to bring to proper level. Returning under truck to install drain plug, I noticed coolant coming from rear of the engine(right side). And of course Ford has changed the cooling system cap, so I wasn't able to pressure test it to pinpoint the leak. Started the engine and seen coolant coming from the left rear as well. I've been reading here to see what others have been seeing, (EGR cooler, head gaskets). With all the heat shields,not much room to look.
After work I did go and buy the adapter to test the cooling system. With any luck I will be able to see leak better.

I've topped up the DEF and the warning is still showing that I'll have reduced engine power within 45kms.
Its weird, just yesterday it showed 550kms to empty so I added one full container, all day it kept showing less and less kms' til empty. Warning lights and bells etc.
This evening topped it completely and still shows. Is there a way to reset it without having to stop at the service dept.

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?

I 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.....

I 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.....

My 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.
