Even though all four tires have the correct tire pressure, the light will stay on if the pressure in the spare tire is incorrect. This is because of a sensor in the tires.
It can.
It means you have a problem with the transmission. Take the vehicle to a trusted transmission professional for repair.

Low oil pressure or a defective oil pressure sending unit.

Why in the world would you want to do this? If the sending unit is defective then replace it. If the light is on you either have low oil pressure of the sending unit is bad. Low oil pressure will ruin your engine.
Have you checked the spare tire yet? I hear that if the spare is too low the light will stay on.
Check the pressure in all of the tires and inflate them to the pressure indicated on the door jam. The light should go off within a few minutes. If it stays on then you have a bad sensor in the tire or on the car.
A drop in brake fluid pressure (caused by, say a leak or crack)
