OK, driving today my and oil pressure gauge dropped to nothing and the low oil pressure warning came on. then it started to fluctuate would stay off for a minute then come back on. Truck still runs fine, no noises, full of oil. I am assuming the oil pressure sensor wire is loose or the sensor is bad. Has anybody seen anything like this? Where is the sensor on the engine? Any help is appreciated.

Thanks Bismic. I'll get over to the dealership and get the parts.
