This time, I wasn't going to waste my time and money at the dealer. The dealer did warn that the DPF had probably accumulated a great deal of ash and may be near the end of its useful life.Ībout three weeks ago and 40k miles later, dreaded P242F appeared again, along with P1451. A new turbo and $7,000 later, the truck ran perfectly and the check engine light was off. Despite steam cleaning the DPF I was unable to clear these codes and eventually sent the truck to my nearest dealer (4 hours away). At approximately 100k miles, this truck first set P1451 and P242F codes. I'm an ASE certified Master Technician and maintain a fleet of vehicles, including a 2007. After learning a great deal via experience, I hope to share a little bit back here.
I have never posted here before, but have spent a great deal of time on this forum and other Cummins and diesel forums looking for information about this code.
