Hi. Thanks for asking your question and requesting me! I will try and help you out.
The system will not attempt a regen with the code 3246-16 present. The code indicate a high DPF outlet temp. This code is caused by one of two things.
The first is the oil from the turbo failure is in the DPF and burning and causing the DPF outlet temp to rise. If you haven't already, the DPF will need to be removed and cleaned.
Second is a faulty DPF outlet temp sensor. If the DPF is clean and has no oil in it, I would consider replacing the DPF sensor box.
Please reply back if you need more help or have more questions. I am happy to assist.

Is the sensor located above the dpf, part no(###) ###-#### ***** a sensor probe of each end and fitting
For hose off each end?
Technician: Cat Man, Cat Engine Expert replied 8 years ago
Yes that is it.
The sensor box has a temp sensor at each end of the DPF and a pressure sensor at each end of the DPF.
Let me know if you need more help.

Sorry took me so long to respond, no one had sensor box in stock. I replaced sensor today but code 3720-15 comes up, particulate filter ash load-high moderate severity (2).
Will this clear by running a regen, I have been able to run manual regen on (1) before but et don't let me for (2) or (3). Will this have to go to dealer?
Technician: Cat Man, Cat Engine Expert replied 8 years ago
Thanks for the update.
If you are getting the Ashe load high. It will need to go to the dealer. To get rid of this code, dealer factory passwords will be needed.
Let me know if you need more help. I am happy to assist.
