2003 Subaru Outback OBD2 P0483 code

This code came up with OBD2 testing. What is the probable repair to the car? THE COOLING SYSTEM SEEMS TO BE WORKING BUT THE CHECK ENGINE LIGHT IS ON. THE RAIDIATOR FANS ARE WORKING.

i NOTICE THAT THE AIR CONDITIONING IS NOT RUNNING COOL AS IF THE FREON IS GONE. THER IS A SMALL SMELL OF BURNING ANTIFREEZE

THE P0483 CODE IS CONNECTED TO THE COOLING FAN. IN THE CODE BOOK.

THANKS
