If the engine is running fine and no loss of power and no noises i would suggest repplacing the oil pressure sensor,chryslers have had the same problem for years,what happens is the sensor itself starts leaking oil internally and will ebentually start coming out if the connector and that means that the sensor has been compromized,hope this helps

SOURCE: Oil pressure light on at idle
Don't delay on this. Take the vehicle in and have the oil pressure sensor checked. It could be just the sensor or it could be something more serious. A drop in oil pressure could lead to catastrophic engine failure.

DOES IT HAVE A LOT OF MILES ON IT OR MAY BE THE OIL PUMP IS IS GOING OUT? THERE IS A SPRING IN THE PUMP THAT IS A BYPASS FOR HOW HIGH PSI IT MAY HAVE BROKE THAT WILL GIVE YOU LOW PSI.

I have a 99 blazer and ever since I have owned it, it reads lower in pressure when idling, but will go up too 40 while driving. This is normal for the vehicle. If the pressure gets real low, and stays low, it means its time for an oil change.
As long as the pressure goes up when you give it gas, it is fine.

Testimonial: "But why has it started reading low, especialy after the new oil pump was put on. It read a constant 40 even when idling before."
A 1999 Yukon DOES NOT have a vacuum advance. It is computer controlled timing. Low oil pressure is the result of some or all of the following : worn oil pump, worn cam bearings, worn crank bearings. Oil pressure also normally drops as engine warms because the viscosity of the oil changes with temperature.
