Check the oil pressure with a mechanical gauge, if normal replace the oil pressure switch. If abnormal could mean oil pump and engine bearing.

What Ras suggested is the correct procedure but with the labor time it takes to do that, it may be cheaper to just replace the sender and see if it fixes it.
