2017 Silverado 6.6L Diesel Exhaust Particulate Sensor Replaced

- In a previous video (link below) I detailed the service regeneration procedure. This video shows you the diesel particulate sensor (a.k.a. Particulate Matter Sensor) I replaced and a couple tips for removal and install. The old OEM Bosch sensor was #0281006809 which was replaced with #12685369 for my model. Make sure you double-check your correct and current model number with a GM dealer's database before you order. The most repetitive DTC code I received before this change was P1478 "Particulate Matter Sensor Temperature Circuit High Voltage".
Here's a link to the Service Regeneration Video:

Thanks and may God bless you buddy
Those 2 hoses you were pointing are used to calculate the soot % accumulated on the DPF filter.
Awesome. Thanks for the input!
Hey there! Great video! Thank you! I have a 2019 Colorado Diesel and have a code for that sensor. I saw one video on cleaning one but sounds from yours that replacement is better. What device are you using for reading codes and to run the Regen? I also saw a video from one guy that said he still had to take it to a dealership for them to tell the computer that a new sensor went in. Any thoughts?
Thank you!
Thanks for the compliment Russ! Just open the description and head to the related video on the regen procedure I performed with the Launch diagnostic tool. That should help you out. For my sensor replacement, no additional programming was required. I doubt your Colorado's diesel would require it. Good luck!
Are you still having issues or did this take care of it?
Currently having a P147B code that says “Particulate matter sensor shunt circuit high voltage” has this is third time light has come on and I’ve coded and this the most repetitive code (or closest to the most repetitive). Love your video, sry easy to understand. Can’t seem to find the sensor anywhere to buy tho
Amazes me we can’t drive these new diesels like the old ones we grew up driving. Letting it sit to idle instead of cutting on and off, etc.. it is very disappointing I’m having emissions issues with a 2019 after I bought it.
Hey Lucas, I'm sorry to hear your 2019 is having the same issue. I've had no issues since I change the sensor and performed the service regen. I had to get mine from the dealer so it was painful on the wallet, but worth it. I agree, there are so many different models on the net that look like a match, but just make sure the dealer confirms you have the correct replacement. Your 2019 will be rolling smooth again!
Hey just wondering what code you had to know what to replace
The most prominent code was P1478 "Particulate Matter Sensor Temperature Circuit High Voltage". Other codes were P0421 "Catalyst 1 Low Efficiency", P0422 "Catalyst 2 Low Efficiency", P118B "Particulate Matter Sensor Temperature Sensor Performance", P118E "Exhaust Gas Temperature Sensor 1 Performance - Engine Running", P142B "Particulate Matter Sensor Control Module High Temperature", P1435 "Particulate Matter Sensor Control Module Temperature Sensors 1-2 Not Plausible", P144E "Closed Loop Diesel Particulate Filter (DPF) Regeneration Control At Limit - Stage 2 Low Temperature", P1474 "Particulate Matter Sensor Sensing Element Supply Circuit Open", P1475 "Particulate Matter Sensor Sensing Element Supply Circuit Low Voltage"
I have a P24D1 code that shows (Particulate Matter sensor Regen incomplete). And the sensor is not relay doing anything on the scanner as far as any changes. I believe it the same issue you had. I think this sensor may fix it. Did you have to take it back to a dealer to reprogram or just change it and you're good?
Thanks
No reprogramming necessary. Just make sure you have to correct part (see above description). Best of luck!
@@sliceoflife1821 thank you! I appreciate you responding quickly also.
While pulling trailer uphill and going downhill, the exhaust fluid quality appears. Who you know what cause the the problem?
That could be your NOx sensor at the diesel particulate filter. Letting off on your accelerator while going down hill is very similar to the same issue with John Andrews in this video:
th-cam.com/video/lnf5SH3oB4I/w-d-xo.html
He does a real good job explaining the steps to get the ECU to cooperate and engage the regen to clear the issue after changing the sensor. Maybe that's close to your issue. Best of luck!
What made you determine changing that sensor. What was truck doing
I had a P1478 DTC. You can see more by opening the description above and linked video for more info.
Sir did you have to reset the adaptation to the vehicle after sensor change?
No reset or reprogramming was required for the sensor replacement. It was smooth and easy.
@@sliceoflife1821 Thanks for the reply. BMW is clowning me saying I need to reset the vehicle adaptation before they will warranty the DPF.
did you have to remove anything to access it? my 2019 has some sort of cover in that area and i've already busted up my knuckles trying to get at it. yours looks easy to get to???
Sorry to hear about that cover. I didn’t have anything in my way. I wonder if they had issues with debris grabbing the wires or infiltrating the Bosch electronics. Sounds frustrating!
What code number did it throw
P1478. Check out the description above for more info. and a link to the regen video if needed. Good luck!
I was wondering if you could edit your video title. the part you change is not technically the 'diesel particulate sensor' (as GM/Chevrolet see's it). The Specific phrasing for GM/Chevrolet of 'diesel particulate sensor' is related to p2002. I am encountering p2002, which is for a diesel particulate sensor, which is in the DPF part of the exhaust, not the pipe. You description refers to the correct 'particulate matter sensor' term, but throws off anyone searching for the other code/ or part for Chevrolet/ duramax/ GM.
If I have misled you I apologize. There are many terms assigned to these sensors and with the implementation of DEF systems in all new diesels, the names get a little scattered and splattered. Bosch, who makes this sensor for GM calls it a Particulate Matter Sensor. I'll add that as an "a.k.a." in the description and add "Exhaust" to the title matching the other vendors (including GM dealers) that sell this sensor. With my truck approaching 5 years now, I'm due to get the service manual and will research the other sensors throughout the whole exhaust for terminology and function. The bottom line is this sensor is for soot calculation post DPF system for the computer to calculate the need for regeneration cycles to heat and clean the DPF. Thanks for making me think about this more and good luck with your repair.
Sorry, it's Saturday morning, I now see my 2017 is hitting the 7 year mark. Time flies when something's so reliable!
Sensor price please??
Looks like you can buy it on Amazon now for $145.
