if your oil gauge is showing little to no pressure at all but your engine isn't makes noticeable noises then it could be the pressure sensor, I have this problem and they should only cost like 10 of 15 bucks to buy a new one. Or if it is making a noiceable difference in noise it could very well be something with the oil pump, maybe the pick-up tube that hooks up to it could have came off in the oil pan or cracked oil pump or bad oil pump.
The oil pressure sensor is mounted on the rear of the oil cooler under the intake manifold.
It is on the front of the engine, just above the oil filter.

Well, I have an 89 jeep wrangler with a really bad oil leak, and I just found it, it's the oil pressure switch. I can see the oil leaking with the motor running. I called my favorite mechanic and he said definitely, that's the problem. I'm off to replace it now.
