    I replaced the sensor. Do I need to reset the computer by disconecting the battery
    or will the replacement have no effect on the computer?

    If you computer was shooting out codes signaling the o2 sensor circut then in order to reset the computer and clear its codes, you must unplug the battery or batteries...
