Okay I am assuming you checked the level of oil in the engine and it's full I hope , next jack up the car and look at where the oil filter adapter is that the filter screws into it there is a pressure sensor there for the oil and if the filter is leaking oil into the connector it's getting shorted out clean it if no leak is present and the connector is dry then change the sensor
