    Do you have a way to erase the code if it comes on? If so create a code to see if it works, for instance unplug the MAF sensor and start the car. If the light comes on then it works. If not, it needs to be diagnosed to see if the bulb or circuit to it is bad. Make sure you plug the MAF back in.
