    Default tunning out post cat o2

    not lt1 related but anyone know when getting emissions tested (when they just scan the computer) will it pass if the o2s code are turned off, and the o2 are disconnected?
    it wont be throwing a code, but i wasnt sure if when they scan it that its trying to find any activity from the sensor

    It will pass a MO emissions test just fine. It only tests to see if the monitor has been reset and that there are no codes. Does not look for activity at all.

    same with PA. No codes.. monitors (actually allowed to have two not set) will pass.

    lol@emissions.

    I am fortunate enough to live in an area that only does a visual, and I wouldn't even hold my breath on the inspection mechanics checking for them.
