Very important to check your oil at least - make sure it is full. Other than that - the switch that tells the car you have low oil pressure could be faulty, or the vehicle truly has low oil pressure and requires a diagnosis. The only real way to know is to have a manual oil pressure gauge installed to check the actual pressure.
