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 RepliesMy 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.
Just 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 RepliesMy 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 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?
Set 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.
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?
View 7 RepliesI just bought a set of 2013 20" rims for my 2012 F-250. I can't seem to get the tire fault light to go off. I've gone through the "learn" process but it won't read them. Are the TPMS not the same between years?
View 2 RepliesOn a family vacation in our 2013 6.7 pulling a 41ft trailer to the Seattle area from Alberta Canada. Made it to destination yesterday. Woke up this morning started truck and cel on. Bought a code reader at the local napa store and read P206 fault inj 6 open circuit. Any thoughts on driving the truck around with a inj fault? Thought I had read here some where that 6 was the regen cylinder.
View 14 RepliesIn 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.
2011 F250 SD FX4 6.7L (stock)
My fuel gauge on my Sport Trac is nowhere near accurate. Ran out of gas the other day showing 1/4 tank.
I get a little hesitation as well when accelerating.
I'm showing a PO191 fault code which says Fuel rail sensor.
Would that cause a gauge to malfunction?
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 RepliesI have a code for #6 low contribution and a thumping noise out the exhaust. When I turn number 6 injector off the popping/ thumping goes away. Truck is straight piped and deleted. It started doing this after getting on it hard to get on the high way. Sounds like beating an empty pop bottle on something
View 14 RepliesI have a 2004 6.0 with 75000 miles on it. My truck is throwing a P0470 code pointing at the exhaust pressure sensor. my question is do I need this sensor or can i bypass it? When I look up the part it only shows 2005 and up.
View 6 RepliesI have a 2006 F350. It started running rough and white smoke from the exhaust. I did an injector buzz test and found no codes. Cylinder contribution check showed cylinder one was not functioning. I replaced number one injector, cleaned injector cup installed new injector and copper washer. Engine runs the same. If it was a wiring harness issue should that have shown up in the buzz test?
View 8 RepliesI got a "P054F- Idle Control System - Fuel Quantity Higher Than Expected" this morning and again this afternoon. I did a search and the only threads that contain the code are the codes lists and one guy who got the code but no follow up. I found a few instances through Google, but almost all of them said the dealers just reset the code. It seems to happen in cold weather, which we are having. Both instances were in the same situation, remote start warmed up then short town drives. No CEL came on. Anyway, I reset it and I'll see what happens.
View 10 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 RepliesI'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.
