I just started having the same code off and on for about 2 months. I keep clearing and it stays out for a few weeks . It is starting to come on when I drive it a few miles after I clear. The motor also stuttered a bit at low idle. It is running fine after a minute but check engine light is still on. May have to check EGR valve or replace . I have to read up more about it. I think EGR is Exhaust Gas recirculation .... I dont know if it is a valve or a sensor. Jeep is running fine, but I still may look into further.
Sorry thats all I have for now.
