Sure you can but the light is on because something is wrong.Buy an OBD 2 scanner at a local part store for about $35,(princess auto) plug it into the OBD 2 port under the dash (driver side) turn the key to the run position without starting the engine.It will scan the on-board computer and retrieve the code's, it will tell you what's wrong.Then follow the on screen instruction's for turning the light off.It will say something like erase code's or reset computer.If there is a problem with one off the O2 sensor's the light will come back on.Good luck.
