ETC (Electronic Throttle Control) light came on yesterday

While drive to work yesterday, the ETC (electronic Throttle Control) light came on. It was and still is running fine so I do not know what may be wrong with the engine. 

My JKU is a 2013 with 17,000 miles on it. It was built in January of 2013 so it is just over 1 year old and this is the first problem I have had with it. 

I disconnected the battery yesterday and cleared the codes and the light came back on today. So, it looks like it will be making a trip to the dealer. Has anyone else had this problem on a 2013? The warranty should cover the repair.
