have you tryed disconnesting the battery for about 3 to 5 min to see if that will reset the light or you might have to take the car and get the computer wipped autozone or any parts place can put there computer on your car to tell you what the problem is it sounds like it just needs to be reset You could try pressing the yellow button (near your right knee) under the dash - then put key in and turn on while still holding it - let go after about 10 seconds this may reset the sensor. It works with the tire sensor as well.
