2017 Chevy Silverado 2500 DPF Service Regen Performed

After a check engine light exposing a DTC for the Diesel Particulate Filter Sensor, I had a hunch the filter was not being cleaned enough from the regular regeneration cycles due to usual short trips to work and back. Changing the sensor worked and I knew the filter would clog it up again if I didn't undergo the lengthy service regeneration which can last 20-30 minutes and is usually performed by dealers or shops with higher-end diagnostic tools. I was already in the market for a higher level diagnostic tool so I upgraded to the Launch X431. All I can say is this is the real deal and I can't wait to use it again.
Here's a link to the sensor replacement:

Same truck as my friend,and he only has 70k Miles with a clogged or dirty from soot dpf, I never deal with diesel anything so this regeneration deal is new to me.They should do something like this on gasoline engines to clean the cat converter,I will see if my Snap on D8 could complete this function.Nice truck..

[@sliceoflife1821]

Thanks bud and I'm sure your D8 will easily handle this. Also, I agree with you on the gas cats. That would be sweet!

[@VolvoAddict]

I just did it today with my d9 I’m sure you’re d8 can do it my boss has one and was able to do it on a 2018

Clean your map sensor on the regular, like evry 1000 miles small but huge maintenance item

[@sliceoflife1821]

Thanks for that tip! I'm due to clean mine.

[@fredwilliams7893]

@sliceoflife1821 most people say every 5k oil change but i checked mine after 500 miles and it was sooted up already most people just use the oil change routine as a base line but don't know how bad the map sensor soots up so quick

@@sliceoflife1821 use maf cleaner mass airflow cleaner you will be shocked how much soot is on it. The tip of the sensor will look like a small blue bulb when it's clean

Just get an S&B 82-1000 MAP Relocation Spacer and be done with worrying about cleaning it so much.

[@roycenter4551]

Did you have a check engine light on which prompted you to change the dpf? Also, can that tool clear check engine lights and codes with the regen performed?

[@sliceoflife1821]

The most repetitive DTC (check engine light) code I received before this change was P1478 "Particulate Matter Sensor Temperature Circuit High Voltage". Yes, the Launch diagnostic tool (X431) can check and clear fault codes before or after service procedures similar to most diagnostic tools. Good Luck!

I have a check engine light on my 2020 Chev Silverado Diesel 2500 - catalytic converter isn't functioning efficiently. Would this process fix that ?

[@sliceoflife1821]

There's a good chance, but since you should still be under the 5yr. warranty for that motor, I would let the dealer decide the next move. I've heard from others, they usually start with a service regen and see what "bakes off" and analyze each system for flow. Good luck!

[@1961suzieq]

@@sliceoflife1821 thank you! Who can I find to do the regen??

[@sliceoflife1821]

@@1961suzieq Glad to help. Just take it to any Chevy dealer and they will perform the service regen. for you. They may also have other techniques to analyze your cats versus the other systems.

[@shawnl4756]

I have the same issue dealer won’t do a service regen to see what happens they just want to replace the whole filter… still under warranty tho, but DPF filters are on back order thanks to the strikes

[@plutoxdior6541]

delete it.

[@LegacyGenetics]

What brand tool are you using to kick it into a regen? Thanks

[@sliceoflife1821]

I'm using the Launch V431 V+ diagnostic tool. You can probably find a cheaper diagnostic that carries the service regen. function for your model, but just dive into the specs and call them if necessary to verify. Many of these companies are guilty of the dreaded OPUD, "Over Promise and Under Deliver". Good luck!

[@kevinolguin1787]

What’s the name of that device?

[@sliceoflife1821]

It’s the Launch X431. I’m sure they have newer models now.

[@totino5691]

What scanner are you using

[@sliceoflife1821]

I use the Launch X431

[@scottlittle4963]

Hello did you do a video of the sensor that you replaced ? Thanks

[@sliceoflife1821]

Hi Scott. Sorry, I forgot, but I can make one tomorrow and post it quickly. Does that help?

[@scottlittle4963]

@Slice of Life Yes I think it will help. Git couple different things that I'm trying to figure out. Thanks for the response.

[@sliceoflife1821]

@@scottlittle4963 No problem at all. I'll have it uploaded before lunch tomorrow.

OK, It's uploaded now. Good Luck!

You are going to make things worse for you.

[@sliceoflife1821]

Care to elaborate? It was already worse, then better after service regen. So what happens next?

[@allenpardon8211]

@@sliceoflife1821 don’t listen to that guy, look the manual regen has several functions that you can monitor to figure out where your problem is. As a matter of a fact when you take it to the dealer for certain issues they will start with the manual regen to monitor temperatures as they increase to ensure they are coming up uniform but that is a different story. The dpf is designed to be regen so many cycles in its life so the more it’s done the shorter the life will become so only do it when you need to. I have a 2019 l5p with 47000 miles on it and the egr is sticking open but fortunately it’s still under warranty. Good luck.
