First check the oil level if ok Remove the oil pressure switch fit a pressure gauge, start the engine an check pressure at fast idle for several minutes, if the pressure falls the oil pump pick up filter is blocked . Have to remove sump clan out sludge and clean filter.
Sometimes that light means overfill oil Sometimes after changing oil if they put too much that happens Check the oil level on cold in level place (give it like an hour or so) for the light to reset If after that the light still on take it to a tech.
