Eventually yes. It takes several reading of the sensors registering a fault before the light illuminates. If you have a code reader...may see that a fault has occured, but the light hasn't come on yet. Again, this is because the sensor hasn't registered the correct number of faults yet:

(see the 2nd paragraph in the 3rd bullet)

Not all countries have the same OBD II mandates...nor did they occur at the same time for all countries that do:
