Do you know what the actual code is?
You can reset it with a scan tool, but the light will only stay off until the sensor sends a bad signal again, which will in turn trip the computer. If you reset it and it comes right back, odds are good the sensor is toast. Less common would be either a wiring open or short circuit.
Depending on what state you live in, you probably won't pass your next inspection/emissions check if the light is on. Just something to be aware of.
