Why does my GMC Sierra have a low oil pressure light?
If your Sierra’s sensor has gone bad, it’ll shoot a false low pressure reading to the ECM. One of the first things that people do when they have the low oil pressure light is to change out this sensor to see if that rectifies the problem. Here’s a good article on how to check the oil pressure sensor from itstillruns.
When does the oil warning light come on?

What causes low oil pressure on a GM 5.3L engine?
GM has encountered numerous oil pump failures with the 5.3L engines produced from 2007-2013, resulting in a loss of oil pressure due to sticking pressure regulating valves. On these engines, the oil pump is mounted on the front of the engine and is driven off the crankshaft at twice the speed of a camshaft driven pump.
