If your car is running good you can undo the battery for a few hours it should reset the sensor. Some of these lights are programmed by the auto engineers to get you back to the shop. If you have no other problems with the vehicle try re-setting the electronics by safely disconnecting the battery at the negative terminal, wait a few hours in case there is a back up memory for short outages, and see if the light stays off. You'll have to reset your clock, and presets, but the light may go off and stay off with no adverse affect to your vehicle.
