If they are readyness monitors that havent passed, depending on which ones it could be.
A readyness monitor scans a particular system, ie oxygen sensor heater circuit, evaporative system and others, to see if there are any issues. You driving the car thoes miles will help but some need other peramiters to run. Some need coolant temp below X degreese, and others need it above X deg.... while still others need to be driven for x amount of miles with below a half tank of fuel or whatever. Some are pretty specific.
