no it won’t pass,even though the light went out ,it still stored the trouble code in the computers memory…so you’ll have to change the faulty o2 sensor and drive it till the code clears its self then take it in to get the inspection

In Mass you cannot pass if the light is on when taking the test

yes it is possible, if the light is coming one due to a short or something else, then it can still pass. I have had this issue with 2 of my cars so far, both kept passing. Now if something is actually failing, then no it wont pass as it will be stored. But sometimes it is just a fluke that it is coming on, even more so if it is turning itself back off. Most emission tests are free anyway.
