Thanks for asking your question. I will try and help you out.
Most often this problem is caused by a faulty ard head or plugged filter fittings. Since these have been changed. There are only two other things I have seen cause this.
First is a temp sensor reading wrong.
Second is a faulty new ard head. 1 our of 4 ard heads I buy are bad out of the box.Please reply back if you need more help or have more questions. I am happy to assist.

There are three temp sensors. One in the ard head. And made together are the turbo out and flame length sensor. The flame length sensor is downstream of the ard head in the pipe. That’s the one. The flame length and turbo out are made together.
Please reply back if you need more help or have more questions. I am happy to assist.

The one I need to replace is the one coming out of the turbo ,next to de ARD HEAD ??
Customer reply replied 8 months ago
Or the one that is on top of the ARD HEAD ?
Mechanic: Cat Man, Cat Engine Expert replied 8 months ago
Actually it’s the flame length that’s downstream from the ard head. It’s made together with the turbo out sensor so you’ll be replacing both.Do you have any other codes other than the 3719-16?

Customer reply replied 8 months ago
No other codes , when I replace the ARD Head and the fittings , I was able to perform the ash cleaning, and the stop engine when off but unit was going out and it ask for regen again, and stop engine is on again and with that code.
Mechanic: Cat Man, Cat Engine Expert replied 8 months ago
Thanks for the information. If there are no other codes. I suspect temp sensor or the ard head.

Customer reply replied 8 months ago
Remove the temp sensor and it had carbon I clean it , start the regen and during the regeneration al active events disappear, the regen fail so to temp too low again but I don’t have ck engine light on ,
What should I do ? Road test ?
Mechanic: Cat Man, Cat Engine Expert replied 8 months ago
I would try a road test.
