I'm keeping my 7.3 forever!

Maybe I'll get a third.

WOW just WOW I know diesels cost more to buy and maintain but... $2300- there are places that will sell a warrantied, re-manufactured gas engine for 1970-1980s trucks AND install it (they get the old engine core) for around that price. I'm surprised they didn't remove the DPF housing and apply some heat with a torch and try to remove the sensor, That would void the warranty on the repair...probably ...
..

Yeah I know what you mean I have a 71 F350 and a long block 390 only cost like $1900 I think I even found one for $1600 or so. I haven't replaced the engine in it was just pricing one time so I would know if I needed to. The aluminum radiator both of the 08's had to have was $1,100 for each too of course they were not covered under warranty after 36,000 miles either.

Ouch .. on the radiators - The price of the new DPF got me thinking and found some sites that clean dpfs (all sizes no limitations, {DPF Regeneration, 1-800-634-3010} )

I would request the old unit back at the very least- may be able to have it cleaned for the 08 if it should have the same problem again.... Gotta be less expensive than Fords new price and if nothing else- they don't get the scrap price out of it, you do.

From what I was told by the dealer the dpf itself was fine. The issue was the dpf sensor failed and they were not able to get it out of the dpf housing and that's the reason the dpf housing had to be replaced. I think I am going to take the dpf sensor out of my 2012 ram and put some type of high temp anti seize in the threads. Thumbsup:

I appreciate the info on the site you found. Thanks.

i think i'd ask for the housing.. you never know.. you might fiddle with it and get it out youself. might be something you can drill thru, then use a small file and cut it95% in a couple places.. once it is weakened and relieved in the center.. it may then extract.. etc. BTDT on some probes and plugs, hollow and solid in tractors.. etc..

I've been thinking the same thing. At the very least I can see just how "stuck" the sensor really is.

There was an article that the same thing happened to an ambulance which was transporting a gunshot victim in DC and it quit on the highway.

I had the same exact thing happen to my 08 model and it only had 66k on the odo. Basically if the RTD sensor goes open circuit it gets interpreted as the maximum temperature possible = the system is on fire. Therefore they shut the engine off. There are 4 of these sensors on the system. I don't know if the engine shut down occurs if any of the 4 sensors fail, or just a specific one, but I know that I ordered the 4 replacement sensors (they are not covered under warranty) and I plugged them in to the wiring harness and cable ties the actual RTD's and cables away from the exhaust. Then disconnected both batteries and left the truck for an hour so the storage capacitor in the ECU could dissipate. When I re-connected I could start it. It went into limp mode because it knew that all the RTD's not heating up couldn't be right, but I was able to drive to the dealer instead of getting it towed (and get all my crap out if it).

The truck sat at the dealer from Nov until Feb (most of the winter) because every dealer in the area was months behind in warranty work and the trucks for people that had businesses had first priority and me Joe citizen was out of luck.

Perhaps the length of time, or the penetrant I put on it, or the frost action worked, but they were able to get everything out without any damage.

Update: 1 year later and the DPF has failed. Mileage under 80k. Tailpipe is black. I have to think about how to approach this at the dealer. I am not replacing it on my dime. But I do not know if federal law allows the dealer to return your truck with a known defective emissions system. I'm not getting the $2300 squeeze put on me for this POS system.

glad it was of interest, I have to admit that DPF woke me up to the price of some of the newer emissions equipment (again)..

Seems to me- there was a post about the feds not allowing the emissions equipment to be (non warrantied) somewhere on TBN also seems like westcliffe01 is alluding to the same thing???

If the housing is made out of an alloy like inconel then the threads will gall and there's not much you can do to repair it. There are compounds that you can put on the threads to help prevent this from happening but unless they are safe to use with the sensor I wouldn't use them.
