O2 sensor and other emission CEL codes are not equivalent to smog test levels. Of course, you can't pass the test with a CEL. You say that the car is on the edge of triggering a code but it still could be WAY out of compliance for the smog test (or it could be within the limits).

I would suggest getting a smog pre-test done to see where the car really stands in terms of smog compliance. Many shops will do them cheaply and don't report the results to the state DOT/MOT.

Having the actual numbers will go a long way in helping you to decide what needs to be done in order to get back in compliance (and you'll know for sure whether you a long way off or really just need a nudge to pass the test).

Knowledge is power.
