Hello, welcome. My name is Mike, I will do my very best to assist you with your question. I apologize if you have been waiting long for a response.

Have you noticed any symptoms with the vehicle other than the light coming on?
Customer: replied 4 years ago.

No there are no symptoms... all seems to be well...

Expert:  Mike Kelly replied 4 years ago.
The issue that you are having and the fact that you don't have any symptoms is consistent with a failing oxygen sensor, this turns on the light because the emission readings are not correct. This will not hurt the vehicle to drive this way. The oxygen sensors would need to be ohm tested.
