Basically, the oil pressure sending unit is what sends the oil pressure information to the car’s computer, which then controls the related lights and gauges.

What is the oil sending unit do?

The oil pressure sending unit regulates the flow of oil. It sends the oil pressure information to the car's computer, which then controls the related lights and gauges. For example, if lower than normal oil pressure is detected, the pressure sensor will make the gauge in the car reflect an Oil Pressure Warning Light.
