Experienced my first Limp Home Mode yesterday on the 2011 RT-s. It had been running rough before I left for work in China before Christmas. When I returned last Saturday I was ready for a ride but lots of catching up work around the house was necessary. Friday was nice so that was the day to ride. Got as far as 2 miles from home and the check engine light and orange screen appeared. I have all the updates so I was able to return home with a top speed of 43 MPH. Called a couple of dealers all about 75 miles from here to see about service schedules. The last one I spoke to was Ted at Havasu Powersports in Lake Havasu AZ. Told him my problems and gave him the fault code of P2279. I had already looked it up and found that it had to do with the TB's. Ted said yes bring it in and they could get to it next week but first he wanted me to check the 2 small vacuum hoses connected to the base of the TB's. He said that they are seeing vacuum leaks developing there as the rubber hoses get brittle and crack. It took about 20 minutes to remove the tupperware and then locating the hoses. At first I could only see the rear hose and it showed signs of cracking but still was flexible. Finely found the front hose and after feeling around I found multiple cracks in this hose. Had to run to town to get new tubing and struggle to replace both hoses. Very little working room but by removing some additional components and cutting some wire ties I got both hoses on. Now for the test. It started right up and idle quickly came down to 1400 rpm's and ran smoothly. Mission accomplished. Thanks to Ted's advice I did not have to load it on the trailer and haul it to the shop. Moral; if you see this code check the vacuum hoses first, it might save you a dealer visit.
