CA smog check woes

My 135 was going to limp mode relatively frequently, and also showed the SES light. Scanning would give Error 6 (small EVAP leak) code. Last week, suddenly the SES light disappears. At the same time, the car now tells me that it needs service. I am not sure if a simple service interval triggered this, because previously it would tell me that service was due 3000 mi away.



Anyway, with SES off I tried to do the smog check. It did not pass because some readiness flag failed. Those are Oxygen sensor and Catalytic converter. Not sure exactly what brought the reset of those flags, but I am now going to drive 60-70 mi and try again. I am on the original (2008) battery. No signs of battery abnormality.



Advice? Should I look at replacing the oxygen sensor? If it fails, shouldn't I get a fault code?
