You first need to remove the oil sending unit from engine and put a oil gauge in its place, so you can check oil pressure corectley. This way you can rule out the sending unit as being the problem. ----------------------------------------------------- In my case, it was bad oil filter. before ever thinking to change the oil pump, sensor or gauge, change your oil and filter, best to make it 'flushed' (2 oil change).
