The light is on because the ECU has detected a problem with the emission's system. Can it do damage to continue driving the car? Not likely if it appears to be running ok. But there is always that possibility. Have the computer scanned with an OBD2 scan tool. The code it retrieves will tell you what part is being effected. Not necessarily what part is bad, but which part is being effected.
