HI,
If it is not making a noise such as knocking or clacking at idle or when slightly revving the engine, then it is likely the oil pressure sensor. If it is making a noise, then a possible oil pump issue.
To confirm, the oil pressure sensor should be removed and a mechanical oil pressure gage installed in its place and actual pressure checked to see if it is within specs.
The oil pressure sensor is located on the side of the oil filter housing that the oil filter screws onto.
