Oil change was done ~4 weeks ago. The light has been on every since that day.

I replaced the sensor last night. After replacing it, I started the car in the garage and let it run for 2-3 minutes before turning it off. It did not throw a light that time. However, it has every since I started driving it today and turning it off.

Are you saying the warning light will clear itself? I'm only puzzled because it did NOT come on last night in the garage after immediately changing the sensor. It came on after driving it today and turning it off,which makes me think the sensor was not the problem.
