Need help to force regen

[Ryan Rønning]

My dash is telling me to drive to clean diesel particulate filter and giving me the wrench symbol. I have driven almost 400 miles trying to get it to go into regen. I have had no luck. Any help would be appreciated. I tried to use the search function but my phone is not cooperating with me

Another possible symptoms I can't get my engine to warm up very much 130 degrees is my maximum no matter how much I drive

Your thermostats are probably stuck open and not letting the truck warm up. Not sure how to force a regen tho.

I hadn't thought about the thermostat. I will check on that. Thanks.

Here are the codes i pulled.
O2002 particulate trap below efficacy
P2452 evaporation valve stuck open
P0128 coolant thermostat below temp
P2463 definition not available definition
P2452 switching valve stuck open
P0128 thermostat not hot enough
P2463 definition not available.

You need to put thermostats in it first.

The 2463 indicates the filter has accumulated it's max level of uncleanable soot.

There's a pressure sensor code there, (2452) have a look at the sensor on the DPF at the front, betcha it's melted. Seen a bunch of these melted.

Replace that sensor if it's melted (its either melted or dinked, there's a circuit concern, or unhooked based on that code), and put thermostats in it and see if it will regenerate. It likely will not at this point based on the 2452 code, because the PCM can't see the pressure in the DPF.

You should still be covered under powertrain/emissions warranty I would think as long as you're under the mileage requirements.

Hope this helps. Let me know if you need any more help.

You may need to remove the DPF and have it cleaned at a cleaning facility, or replace it, based on the 2463 and not knowing any more info about the truck.

Even if you do get it to regenerate at this point I think you are still going to have issues down the road. Every truck I've worked on that's thrown a 2463 has needed a DPF not long after ANY diagnostic repairs were performed.

Time for a delete pipe

As an aside, to the original poster:

That is a BAD *** truck. Love it.

And hdfatboy - Don't you mean a high sulfur pipe?

Yup i meant a high sulfer pipe

I climbed under it and didn't find any of the sensors melted. I unhooked the 1 that has the vacuum line attached to it and then went for a drive it went right into regen mode then and cleaned out the filter. Disaster averted for now. I have a line on an H&S XRT PRO and I will be getting a delete pipe to go with it
