Evantually it will go away by itself once you computer goes through its repeated cycles and finds no other faults. However if it is that much annoying then you can reset it FREE at most 10 minutes lube places. Here in NJ Jeffy lube gives a reset for free for the green lights (oil change meter) plus check engine light when you change motor oil. THIS IS MINOR!
Also I can tell you what to do so you don't have to wait for autozone! get yourself a code reader/reset tool for about $135 from www.peakresearch.com
