    For any monitor to run, all the "enabling criteria" must be met for that particular vehicle. You would have to know the specific requirements to be sure if the driving conditions were met, regardless of mileage. The O2 sensors are required for the monitors you have listed as not running, and are tested before the others. They have to be in good condition and their heaters have to be good as well or the other monitors will not run. Also, out of range fuel trim or ECT signals and too many misfires may prevent those monitors from running, as well as pending codes which do not set the CEL.
    When I'm good I'm very, very good and when I'm bad I'm HORRID.

      I threw my computer away. I can sleep now. Isn't it anazing that a carb car doesn't need a computer to run?
