Hi. Thanks for asking your question! I will try and help you out.
To get rid of the 3719 the engine needs to complete a regen.
If 3830is active. It will not start a regen. This code indicates a sensor fault with the secondary differential air pressure sensor. Most likely a faulty sensor but could be a wiring problem. Once this code is not active. The system should regen.
Please reply back if you need more help or have more questions. I am happy to assist.

That's the problem. The sensor is showing me low pressure, so it should go into regen mode. Just can't clear code. Does it have to go to dealer to have code cleared or should it clear on it's own?

What numbers are after the 3830?

FMI 3
Technician: Cat Man, Cat Engine Expert replied 2 years ago
Thanks for the information. -3 is an open circuit. If it is active the sensor is either bad or there's a broken wire in the harness that connects to the sensor. These codes do not need to be cleared at the dealer.
Please reply back if you need more help or have more questions. I am happy to assist.

Do you know of where I can buy Cat ET software? My local dealer will not sell it to me. I used to have it, the subscription ran out & they will not renew it. Told me I have to bring it to them, that I am their competition.
Technician: Cat Man, Cat Engine Expert replied 2 years ago
Oh yes. I have seen Cat dealers do this my friend. It's very frustrating. Many dealers will not see it. The only place online I have seen folks get ET is at :
http://www.mhhauto.com
They can get you et and license it. I think it's free. Just sign up and become a member. Then find the chat room for Cat software. I know many people have gotten it there.
Please reply back if you need more help or have more questions. I am happy to assist.
