Low Oil Light

I've got a 95 3.4 V6 with about 175k miles(about 150k highway), I turn the car on, and the Low Oil dashlight is on (generally meaning that the oil is low...:banghead: ), however, this is not the case. The light began coming on about a week ago, so naturally, I checked the oil level, it was sitting right on full. After running the car long enough for the oil to work it's way up into the engine, shutting it off, and starting it back up again, the light is no longer on. Oil pressure stays at a very good level according to the gauge. Yesterday, I went and had the oil changed, but the light still comes on! I'm stumped here, and that damn light is worrying me to death! Any suggestions?

It's probably a sensor that is bad, that might show up on the codes if you can get the codes read maybe that will point you in the right direction. Otherwise find out where the sensor(s) is/are and replace it/them.
