My check engine light just came on and a few miles later the "exhaust fluid system fault" also came on. I plugged in my scanner and these codes came up:
P2479 b1s2
P2033 b1s2
P050E
P0231 b1s2
I'm assuming these mean bank one sensor 2 is bad. Need to verify? I don't remember all these codes when the #4 sensor went bad.
2014 F250 Diesel... I got the msg saying 50 miles until speed limited to 50 mph. None of the earlier warnings re adding def. check def on computer and it said it was ok. I even added def and it only took a small amount until it overflowed. It was more than 1/2 full. The error message did not reset. I drove it around for several miles and it still would not reset. Having it services as we speak, and the tech is still having difficulty running down the cause. He has done a regen,and reset the computer and etc and still has not resolved the issue..
View 14 RepliesI bought my 2015 F250 last November, and this spring my check engine light comes on with the message exhaust system fluid fault with the anoyying speed limitation. Bring the truck back to the dealer and they just say add def fluid, so I just have them do it. 2 weeks later the message comes back, bring it back to the dealer and they tell me it "needs reprograming" they do the work, light goes off. two weeks later light comes on again. Dealer puts in new exhaust sensors and reprograms the truck.
This fix lasts a few months in the mean time the truck shutters really bad under regeneration mode. Talk to dealer they claim its normal. Finally this week the light comes back on again. Bring the truck to the dealer and Ford keeps telling them that it only needs reprograming but that doesn't fix the problem. The dealer wants to replace the computer but ford isn't letting them do it (the truck is still under warranty) . I am starting to get pretty mad when I went out and bout a 65k truck not to have these problems.
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!
View 14 RepliesJust wondering what this could be.its giving me the 50 miles to 50mph max speed. Def tank is half full.truck runs fine.
View 2 RepliesSet out for a 450 mile trip this morning. Checked all fluids, then checked the Edge CTS for any DTC's since it had been several weeks since I had driven the truck more than 100 miles per day. No codes except for a couple of P0000's.
Good to go.
45 miles into the trip while traveling at 75 MPH the chime sounds and the message center says "Diesel exhaust fluid fault. Speed will be reduced to 50 MPH in 50 miles." CEL on too. Using the CTS, I checked the codes:
P20EE - SCR NOx Catalyst Efficiency Below Threshold (Bank 1)
P2080 - Exhaust Gas Temperature Sensor Circuit Range/Performance Bank 1 Sensor 1
They were in the order shown. So the EGT fault came first, followed by the NOx fault.
I really need this truck today. Cleared the codes, but of course that didn't work with the 50 MPH limiting. Went back home and got the Jeep. The truck is about 1 mile away from the 50 MPH speed limiting.
It would seem that the EGT problem could lead to a NOx issue, but I could be wrong. I monitor EGT1 with the CTS, but I didn't see anything out of the ordinary. Also I thought an EGT fault usually gives the "Stop safely now" fault.
I did take a picture of the CTS DTC display before clearing the codes. Hope that will work for the dealer.
I had a ford technician plug in and check my CEL. Says P246E, Bank 1 sensor 4, exhaust system fault. I am leaving for holidays in a couple of days but dealer to busy before I leave. Is this something that will leave a guy stranded on the side of the road? I've already been towed once...
View 5 RepliesSunday I received the dreaded DEF system fault message on my 2012 CC SRW SB FX4 with 7800 miles on it. Warned me that speed will be reduced to 50 MPH in 50 miles. I have a CTS Insight, so I checked for DTC's. First one was P2200 - NOx sensor circuit (Bank 1, Sensor 1), the second one was P204F - Reductant system performance (Bank 1).
After 50 miles it warned me that speed would be reduced to 50 MPH on next restart. Sure enough, Monday morning speed was limited to 50. I took it to the dealer, but I should have left it running. When the service guy started it, the fault had cleared and it no longer showed the P2200 NOx sensor code, although the P204f code was still there.
My question is, why in the world would Ford make it so that the code is cleared if the fault goes away, especially after putting you through the 50 MPH limit scenario?
Dealer did a reflash and said its OK now, but I'm not so sure. My trucks build date is 10/6/11. I read TSB 11-11-13 which states the NOx sensor module should be replaced for P2200 on trucks built before 10/11/11. Is that only for a persistent P2200?
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.
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.
View 14 RepliesNew 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???
In the last year I've had a NOX sensor fault (dealer repaired) and a DEF heater fault (I replaced). I'm now getting an EGT sensor fail. Every fault is with the same system.
I'm also realizing that while I'm getting the exhaust system cleaning message, my DEF level is not being depleted.
All the dealership wants to do is change out fault codes but I think the true issue is elsewhere.

Usually in the OBS 7.3 but a buddy of mine with a 2003 6.0 is having some issues. When he romps on the pedal but when he does so he claims he can smell exhaust in the ventilation system. I rode with him and smelt it as well. So I inspected all exhaust clamps and piping as best I could and did not notice any soot or leaks while running. I don't know if it pertains to it or not but his heater only works on defrost.
View 4 RepliesHooked up the toyhauler Friday and before we were off of our street I got the "Wiring Fault on Trailer", brakes on trailer worked, got out and verified the lights were working so we proceeded on.
When we got to the destination the manual says that if the fault stays on when disconnected it is an issue on the truck side, it is still on when the trailer is disconnected.
I just installed a new MBRP 5'' exhaust system in my 7.3. I have only put a few miles on the truck since it was installed and I now have a black thick oily residue in the tailpipe. The exhaust system had some sort of oil in it when it was shipped. I remember getting it on my hands when installing it. I think the oil in my tailpipe is just the oil burning out of the exhaust system which mixes with soot that turns it black. When I installed the new up-pipe, the exhaust side of the turbo was dry. Like I said, I haven't ran the truck many miles with the new system yet. A few friends of mine have looked at the exhaust and they think I have a bad turbo seal. I didn't have any oil in the exhaust with the old system. It was sry. My truck has 135,000 miles on the original turbo. I hope my turbo seals aren't bad.
View 7 RepliesIt just came on when I ran up to the gas station followed by the airbag light and the traction control light.. truck ran fine. I've tried looking this up found some people have had this message and there truck won't start.
View 6 RepliesI only get the fault when backing up. Driving forward it's never a problem. The truck is a 2015 F250. We are pulling a 33' travel trailer. Both are new. I was not sure if the fault when backing was something that happens or if it might be indicative of a problem. The manual says it's not an indicator of a problem. Rather, there might be an issue. Again, it works fine when traveling in a forward motion.
View 10 RepliesHave a Gage fault and tow haul flashing on the dash have no clue what is going on?
View 8 RepliesWell, at a little over 10k I have my first issue. My monitor displayed a Tire Pressure Monitor Fault. All tires are OK. Light won't go out. Guess it just earned a trip to the dealer.
View 14 RepliesI just bought a new 2014 f250.
He says since he has purchased the truck the TPS sensor would occasionally go off saying there is issues with the tires. Tires are fine yet the light chimes on after being reset shortly. Been at the dealer for a week and they haven't really touched it I was wondering if there is any know issues.
Also my dad had the truck in 4x4 and when he puts the truck in park it made it a loud clunking noise. Ford is said there heavy duty line was full so they didn't look at that ethier. He needs the truck for the weekend so he is picking it up tomorrow, he will return it when he can but does this sound familiar as well?
Finally got back home and I have the TBC Fault occasionally pop up on the dash and sometimes the C2803 fault code (Brake Pressure Transducer Sense Circuit Failure). Both have happened without the trailer connected. Is it the OEM brake controller? Or possibly the sensor at the base of the Brake Master Cylinder?
