Perpetually Random ESC OFF Light

The ESC OFF light continually comes on which causes the vehicle to not function correctly, especially the shifting of the transmission (others have reported this elsewhere as sluggish acceleration, but the vehicle's automatic transmission stays in gear 4 if you keep it in Drive mode. If you switch to the "sport shift" or "manual mode" where the driver has some control over the gears, then the sluggish acceleration goes away.) But back to the question, does anyone know what is causing this "Dummy Light" to come on? I have seen "throttle sensor" to "brake sensor" and one person even said they told her it was dirt in the carburetor, which is especially interesting since it is EFI. Any help would be appreciated. Thanks for reading.
