Had a similar experience a few years ago. You just have to drive and let some time pass. I tried to do the drive cycle routine but it is difficult to meet all those driving parameters with traffic etc. After two weeks and a few hundred miles some of the sensors still read "not ready". BTW I don't think you should be failing if the car is in a not ready condition.
