OK, a couple of weeks ago I used Forscan to activate the DPF % display on my '15 F350 with 6.7. At that time the DPF % was up and when it hit Full the truck went into DPF cleaning mode and I ran it on the highway but it shut it off at 70%. Fast forward about 160 miles and it is full again so I decided to make a interstate trip into the city. The DPF clean cycle started and at the same time the check engine light comes on. I get about 10-12 miles down the road and I get a warning message DEF ERROR reduced power in 50 miles. At that point the cleaning cycle is at 30% and still going down. I drove another 5 miles and made a turn around at a overpass to return home before this things goes boom. The cleaning cycle quit at that point and it was at 15%.

I called the dealer on the way back and gave them the information I had with the warning message and display. They told me to get it in but before I did I dropped by the shop and read the codes. I got a P207F code and then I took it to the dealer. That was last Saturday and they gave a loaner '18 F150 to drive until my truck was repaired.

Fast forward to this morning I went to check on the status and was told they haven't had time to check it yet. I didn't get angry with them but I did ask if I needed to take it somewhere else if they won't have the time to repair it. I got a call this afternoon from the shop and they told me the truck was ready. The service writer said after my visit she talked to service manager and they decided to take a look at it real quick. She told me that they only had to re-flash the pcm with a updated TSB

FWIW, during all this time I researched the 207F error and got so much information that I wasn't sure what was going to happen. I expected the service manager to tell me bad or low level def and that would be on me, I expected that somehow it would be my fault and I would have to pay for the repairs. That scenario didn't happen. They were cordial when I picked up the truck and explained about the TSB.

I was starting to get a little irate only in the fact that the truck has under 33k miles on it and already spent 10 days in the shop for a new HPFP. Then this happens less than 3k miles later. I even thought I may have caused the problem activating the display with FORSCAN. All turned out well.

I am only posting this because with all the data and horror stories out there about bad dpf sensors, bad def, bad modules all mine needed was a PCM update. I will try to post the pic of the service sheet I received.

Bottom line? Make sure this TSB has been performed on your vehicle before you have issues. I certainly wouldn't wanted to be on a trip and broke down over a simple software update. JMO

 

Thanks for posting this information. I will try to take mine to Ford to get them to do the same thing. Thanbks again. Dave
