My smog guy said it's always a good idea to have replaced the oxygen sensor
prior to testing.  Two years ago my van had barely passed and he commented
that it might not pass the next time.  For that reason, I had a tune-up  and
replaced the oxygen sensor, then made certain it was good and hot prior to
testing, and it passed easily.
