30 seconds

??? On some cars removing it does not reset it....could need a reader...depends on the model and ECU

Don't our cars have OBD II (or equivalent) systems that require a code reader to clear a code? I know that my older cars OBD II and you can borrow the reader from Advance Auto, Auto Zone, and others, to check for codes and then clear them.
