Generally three things can turn the light on. First is the sending unit itself if it's going bad. Next is an obstruction of the pump pickup screen (usually hard carbon deposits). Third is worn engine bearings (usually rod bearings). Best way to find the problem is to have someone put a mechanical pressure gauge on the engine and read the actual pressure. If it's low you need to go into the engine to determine why. if it's normal, replace the sending unit. Senders aren't terribly expensive and you could just buy one and replace the one you have, providing the engine isn't tapping or knocking.
