Is the car parked on an incline? The sensor for this is like a stick that's screwed into the side of the oil pan with a 2 wire electrical connector plugged onto it. If it's not submerged in oil the light will come on. Since the wiring and plug sits down low it's possible that something got kicked up while driving and damaged the connector. Inspect it carefully. If the connector is loose or unplugged the light will come on as well. HTH. -Jim
