Initiate DPF burn off

Hey guys! I have looked on here but have not seemed to find what I am going to ask. Is there some way of fooling the stock ECM to do a DPF burn off. My last "Cleaning Exhaust Filter" took forever it seemed. So I am currently interested in a way to initiate burn off. I know I should just delete the POS but that is not possible at this time. Any ideas would be great.

If I am reading you post correctly, you are looking for away to make the truck go into regen now? Hammer down, the harder you drive the more soot will be produced and it will go into regen.

you could take the pressure sensor off the dpf and make it go into regen.

I have no idea and not sure if it's possible under normal conditions.

Update! I crawled under the truck unplugged the pressure sensor like greasltn suggested and with in 20 ft of leaving the driveway it went into regen. Side note if anyone else is going to do this make for damn sure you have a way to monitor your EGT's. At slow speed(25mph) without hardly any boost the temps were hitting 1200 almost instantly. Put the foot into it a little more and the temps come down with the turbo spooling. Just have to wait for it all to cool down now to plug it back in.

I always wished Ford had thought ahead and put a "manual regen" button or switch in. It seems like it always wants to start a regen when swinging into the driveway instead of the last 30 minutes on the highway...

After seeing greasltn's post above, it got me thinking that maybe tapping into one leg of the pressure sensor's wiring, a momentary pushbutton could be installed in series with it to fool the ECM into initiating regen. Don't know if it would have to be normally open, and a closure to start regen, or vice versa. A simple button/switch installed in the cab with two wires running down toward the sensor would be the extent of supplies needed.

This sounds like a good saturday project, but not really sure about tapping into my $45,000 truck's wiring like that just to manually initiate regen, but it should work!

t613, I was sitting here watching it rain thinking the exact thing you were. Instead of splicing into the harness though I wonder if a real short extension with Male to female ends and the splice could be made cheaply? The problem would be the ends. Might have to take another look under the truck and figure out a way to do this. Just like you mine goes into regen at the most inopportune times. Worst time was driving for 6 hours pulling down my street 50yards away from the house and BAM!!! The message from hell pops up. Anyways! Rainy weekend project I think. Cheers guys! Play safe.

Manual regen would be awesome. Some of our newer dump trucks at work with DPF's have a manual regen switch. I guess they cant really afford to go into regen and lose power with 50,000lbs of asphalt onboard.
