As tech would say, Under that message it could be anything, Most common thing is its the o2 sensors:

When my emissions system service came on(came on 2 different occasions)-

1.)mass air flow sensor
2.)throttle body

you need to pull the codes.

could be an assortment of things. Usually it's the 02 sensor, but could also be a bad ect sensor, bad secondary 02, bad tps (etm), bad map reading, etc.

Best thing to do is pull the codes first and see what they say.
