Ford 6.7L Power Stroke Diesel :: CEL And Exhaust Fluid System Fault Came On

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.

Ford 6.7L Power Stroke Diesel :: Exhaust Fluid Fault With P20EE AND P2080

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.

Ford 6.7L Power Stroke Diesel :: 2014 F250 - Exhaust Fluid System Fault

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..

Ford 6.7L Power Stroke Diesel :: 2015 F250 - Exhaust Fluid System Fault

I 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.

Ford 6.7L Power Stroke Diesel :: 2012 F350 - Exhaust Fluid System Fault Message

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!

Ford 6.7L Power Stroke Diesel :: Diesel Exhaust Fluid Reset?

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.

Ford 6.7L Power Stroke Diesel :: 2011 F450 - Exhaust Fluid Warning 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.

Ford 6.0L Power Stroke Diesel :: TBC Fault Occasionally Pop Up On The Dash - Code C2803

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?

I 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?

Ford 6.7L Power Stroke Diesel :: 2013 - CEL On With P206 Code / Fault Inj 6 Open Circuit?

On 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.

Ford 6.7L Power Stroke Diesel :: Fuel Gauge Inaccurate / Fault Code PO191 - Hesitation When Accelerating

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?

Ford 6.0L Power Stroke Diesel :: 2006 - Code P0263 - Engine Misses - White Smoke From Exhaust?

I 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?

Ford 6.7L Power Stroke Diesel :: Wiring Fault On Trailer

Hooked 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.

Ford 6.7L Power Stroke Diesel :: Trailer Wiring Fault - Only When Backing Up

I 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.
