Tire Pressure Sensor

Does anyone know when tire pressure sensors became standard? I purchased a used 2010 5 this spring. It had the green caps on the valve stems. I assumed it meant that they had sensors. I just put on my winter tires and rims that dont have sensors, fully expecting a light on the dash to come on, but one hasnt yet? My used (new to me) 5 was manufactured in 03/10.

Anyone know?
 
I have a 2010 sport. It has the sensors. The green caps usually mean that the tires have been 'filled' with nitrogen.
 
Well wholly cow! I learned something new today. I had no clue green caps meant nitrogen. Thanks!
And with no dash light showing a problem with the winter rims and tires that I KNOW don't have tire pressure sensors, I will assume now that I don't have tire pressure sensors in this vehicle.

Thanks for enlightening me, pkthomas! :)
