i've been stuck in regen for almost a full tank and 200 miles. did a 50 mile highway run at 75 mph just to insure i was giving it enough time. any way to manually stop the cycle?

 

My guess is you have a bad sensor or something. Since it is a 2008 your dpf is covered for 100K miles.

It maybe bad as well. I'd take it in.

 

glad i asked...i assumed the warranty was for the engine only since i took a screwin from the dealer over a bad water separator. thx senix, ill take it in.

 

100K warranty for the DPF only applies to the 2008.

 

Since I have been working on these 6.4s for a while now I reciently ran into a truck much like you are describing. it had WAY to much oil in the crankcase. I suspected it had a leaking injector, removed the valve covers, then ramped the fuel pressure up to 25,000 lbs of pressure, they were ok, so i made some tests on the fuel pump and they turned out ok. However part of the testing was to drain the oil, mark the dipstick and drive the vehicle for several miles. I noted that it too never came out of regen, so it was decided that that was the reason for being overfull since the operator of the vehicle didnt think it being in regen was a problem. I had done several test which all came up clean, in a act of desperation i admitted defeet and called our tech line, they stated that a "MAF" sensor can cause them to stay in regen. Now in our manuals it asks if there is a MAF code but it doesnt say to check the values on the key on engine off. when I did check it I found it out of spec by a small amount, hardly not enough to really warrent going further with it, however I did replace the MAFand before I made it out of the lot it went out of regen, I reinstalled the original MAF and it went back to regen. So before everyone starts pointing at the DPF and all the other stuff get a good look at the MAF sensor. IF YOUR TRUCK HAS HAD FREQUENT REGENS BE SURE TO CHECK YOUR OIL LEVEL. Remember if you have had the 11b23 recall performed, and your oil level gets overfull it can put your truck in limited power and put it in "limp home" mode... That is not a fun ride home thank you very much. If you havnt got the repair done yet, and you take it to the shop, if they get stuck tryiing to figure it out, you may encounter some resistance when you suggest it may be a possable MAF problem, so be prepared. Good Luck

 

My 2010 has been regenerating excessively I have an appointment to have the issue checked tomorrow.I just did an oil and fuel filter change and drained 18 qts of oil when my last change I purposely only put 14 qts in to make up for the oil dillution last oil change same thing drained 18 qts.I change my oil at 5000 mile intervals this has really got me concerned.I had the 11b23 flash done on it back in june of this year I wonder why it did not go into limp mode or throw a code from oil being overfull I have 18000 miles on this truck and do my own maitenance regularly and use diesel kleen with every fillup.

 

thanks Rik. since my truck has been in the shop 15 times in the last 6 month, i'm assuming that i'm upto date on the flashes so i will check the oil and mention the MAF sensor to the service tech.

 

Hey your welcome, when they fix it let me know I am always curious and since me an toto are no longer in Kansas... well you get the story. Hope the info helped.
Good Luck

 

Good find on your oil level overfull, after the inception of 11B23 we started seeing that overfull condition and when we relized there is no sensor to determine level it made me start asking questions to the silver palace, it turns out it is an algearythim (sorry for the mis-spell) how it woks is cool in one way but scary in another... It seems the software now watches the throttle and the crankshaft in that when you put your #10 on the noise pedel it expects to see a determined crankshaft speed, (kinda like cause and effect) however if you have diluted oil now the crankshaft spins faster for the same pedel movement. So when it see's enough of the crank speed increasing it knows you have fuel in the oil. So all that said you can see a lot of variables, like very good oil not breaking down as fast as others or the dilution rate was not big enough or the ambient temp was or is very cold. Try to remember how often it is going into regen cause it will be important info for the shop. If it is a Ford shop they can see when the last regen was compleated and how "loaded" the DPF is when they are testing it. I just went on line and confirmed that Ford says regen can happen every 100 to 668 miles depending on variables, that most regens can take 10 to 40 minutes and that if driving speeds are 30mph or below that time can go concierably longer.
My question to you is: does your dash readout state constantly vehicle is "cleaning exhaust" or do you have to scroll thru your menu to verify it is doing it. reason i ask is since 11B23 now when the truck regens normally now the readout only flashes cleaning exhaust for 4 to 6 seconds then goes to normal instrument cluster operation, however if the message stays on thru out the entire cycle either tyou have not had the 11B23 installed or you have other issues... This information will be important when comunicating to the writer and the tech (concider leaving a note on your dash for the tech, with your phone # where you can be reached if they have questions). One final note, dont bring it in for work with less than a 1/2 tank, contrary to belief were not joy riding were driving it to watch what it does and to compleat testing. I know several techs that say when they come in on empty they cant be bothered to get fuel for it... So guess how good that diag is worth!
Good Luck

 

One important thing to note is that if you haven't had the new ford reflash, and your oil gets high enough ....your gonna have a runaway engine!

 

Thanks for the info guys as for the clean exhaust filter message every since the truck was new the message would stay on for 4-6 sec. as you described I would have to scroll through the message center to know when it completes which lately it takes exactly 40 min. to finish even when I am on the expressway driving 65-70 mph.But you are right every since it started getting cold my regens has lasted 40 min. when back when it was warm it would only last 20-25 min.

 

So did you get it looked at?

My empty regens are only about 10 miles...or what is that 10-15 minutes and my last one was at 587 miles.

I hardly ever run empty that long though.

 

I got the truck back today this is what ticket says [Customer reports vehicle regens every 30-40 miles.Performeddata logger PID monitor all systems checked out OK.Performed manual DPF regen operation and reset DPF table.]I cannot understand what it means could someone please explain.Weyland426 I apologize for hijacking your thread.

 

they did a forced regen without driving it.. and cleared the stored computer information used to cause a regen while u are driving.. net.. they reset the system and cleaned it out..
