I know you probably have fixed your problem but this just happened to me for no reason. All systems seemed go so before I connected my OBD reader I tried the trick used for resetting the oil change reminder. Turned the car to run, but do not start it, pressed the accelerator pedal three times holding it down for one second each time. Turned the car off and then restarted it and the trouble codes went away and the cruise control started working. It did not happen again. I am assuming there was something on the sensor and it threw the code when we first started the car. Until reset it stayed on. Once reset it did not return. Just a shot in the dark for you. I got lucky.
