Dodge Particulate Flilter info.

[Bobby A]

Moderator, please put in appropriate area.

My 07 Dodge Ram overhead chimed today indicating 80% particulate filter full. I was told to drive the vehicle on a freeway for 45 minutes to clean off the filter. My question is the freeway is about 25 miles away in kind of city driving, can I make it to the freeway without clogging up the filter 100% and shutting down the truck ??
Suggestions and help please !!

Thank you,
Bobby A

you dont have to travel down the highway, just sustained speed of 45 if i remember correctly. im sure that 25 miles will be fine when you take into account how many miles it takes to get it that full. turn your eb on and head to the highway

It doesn't have to be an actual freeway. Anywhere you can drive at 50-70 mph without a lot of stop and go. "City driving" is what you want to avoid. Put her in tow-haul mode, lock the tranny to 4th gear max and drive it like you stole it.

Thanks Brett & Bob, thats what I'll do tomorrow. The Dodge DVD/CD they gave me says to drive the vehicle at 50 MPG for 45 minutes. I figured I could get on the freeway and blow her loose ( drive it like I stole it ).

It doesn't take 45 mins. Mine takes 20 mins. when that signal shows , which is rare.
Actually you will see the numbers go from 80 to 70 to 60 then the warning will go off but the regen will continue until about a total of 20 mins passes.

Thanks for the info, a thought just occured to me. I'm wondering if depending on the software/flashes thats been done on a perticular truck if the procedure you described would be the same?

Mine has all but the very last flash offered. If I remember correctly the first one or two made adjustments to the regen cycle way back in '07 and '08.
You only see the overhead warning after the truck has made several attempts at a full regen but didn't complete because of slow speeds or engine was turned off. I have the Edge Insight Monitor that displays many engine parameters depending on choice and one of those I display in "regen cycles" so I can see everytime the truck attempts a regen. If I have seen that 3 or 4 times and was running slow or turned off engine prematurely then I take a 20 min. ride somewhere to allow the next regen to complete.

UPDATE :
You were right, as many suggested I kept the truck in 4th gear maintaining a speed of between 50 and 60 MPH @ between 2000 & 2500 RPM's. The display was reading 80% full than a few minutes go by and then read regen in process, a few more minutes go by and then it read 70 % full, I new then I was heading in the right direction. A few more minutes went by and I heard a chime and the display read regen complete. I was very happy!! I got to the freeway and turned around and came back to home, maintaining the above MPH & RPM's most of the way home.
Thank you all for the great help and advise.
