Is the oil level full and clean? Also, have you checked the oil pressure switch to make sure the wiring and connector is in good condition? Also, check to see if there is any oil leaking from the sensor.
Here are the directions for replacing the pressure sensor. I'm adding them so you for location and if you find it is leaking, it will need replaced.
