Hello I have a Cat C-13 with an active code 3719-0 any info on this code
Hi. Thanks for using JA! I will try and help you out.

A 3719-0 code is indicating that the DPF is full of soot and the system is in need of completing a regeration. This code will not clear until a regeneration has completed.

Please let me know if you need more help or have more questions.

what is causing this looks like diff pressure is 0.1 and ash regen is not required?
What does it do when you try a regen?

Are there any other codes in the ecm?

I see. Thanks for the information.

I have seen several things cause this. The first is a fsulty spark plug in the ard head. You may want to remove it and inspect it. Replace if necessary.

Next is plugged fuel filter fittings. These fittings are up strean from the ard head. They can become clogged and cause regen problems.

The last is a fsulty ard head. I normally start with the spark plug then the filter fittings first.


Let me know if you need more help.

No. The cleaner is no longer used on these engines, they have been upgraded.
