Usually it's an oxygen sensor go to a local advance auto store and they will plug in the computer code reader and do a diagnostic test for free

If it is still under factory warranty take it to the dealership for service. Saying it is usually an oxygen sensor is very misleading. The light can be caused by any number of things.
