Question

The downstream O2 sensor was replaced and the check engine light was cleared and it failed inspection....The reader stated that the evap was not ready

Answer 1

Is the EVAP system the only one not complete? because you can pass with 1 incomplete.

I would drive the car more, 10 miles freeway driving at 60 mph and another 10 miles normal city does it for all the Nissan's we work on that needs a smog check.
