Default CEL, P0519 code

2002 Concorde Limited, 3.5 HO, 166k miles. CEL just came on, did the key dance and got a P0519 code. Cannot seem to find a definition of this code for this model year. The one definition that I did find was for a 2012 Durango and indicated and idle air control problem. The car runs fine and idles fine, maybe just a tad high at 850-900 on the tach. The idle is steady, no waivering. Any ideas on what P0519 means?

Problem solved, the IAC had a very small amount of dirt in the throttle body part of the IAC housing. After cleaning, the code cleared, the idle dropped back to ~750 on the tach and all is well. Guessing, based on the small amount of dirt in the IAC, that they are pretty sensitive. Keep the filters clean guys!!
