Have you tried Google'ng OBDII code ? it should pop up with a description of the code, try Googling with the Pxxxx code +Duramax syntax.

 

I keep getting the B0229 code, when I look it up it says HVAC actuator malfunction but Air Conditioning seems to work just fine. I keep clearing the code and it keeps coming back. One of these days I need to take it in but I have to reload my HypertechIII when I do that.
