Dandy. The Engine Computer will learn the characteristics of new sensors right away, but that can take a little longer when two or more are replaced at exactly the same time. What you're referring to are "readiness" monitors for the emissions system. There are long lists of conditions that must be met for those to run, and it's frustrating because those conditions are different for every car model and year. Your best bet is to visit the dealer, but it's common for no one there to know the answer off the top of their head. Sometimes a mechanic will know one specific condition that is needed but hard to achieve unless you know it. At the dealership where I worked, the service advisers had the owner's blessings to photocopy a few pages out of the service manual if they weren't busy with customers, but things like this are often only found in specialty system diagnostic manuals. You might have to visit a few dealerships before you run into the person with the right answer.
