Sure it will go out after a number of restarts. Here is the rub though, it has to see something like 20 good drive cycles in a row without reoccurence of the fault that set the code and then it clears the light and the code goes pending and then in something like another 20 or 40 cycles it will clear the code entirely. This is a huge amount of time and if the fault code was in fact a fluke well then it will go ahead and clear itself with time, but that is a real long shot. These parameters are all just basic OBD II stuff, all of the manufacturers have to use them as there guidelines when they set up the diagnostics and engine control systems on their car. Keep in mind they are only GUIDELINES and they definitely vary from manufacturer to manufacturer.
