Find a different shop, or if your a DIYer go to your local parts store and get a manual oil pressure gauge and install it in place of the oil pressure sender, as this is just a temporary setup so don't worry about the oil pressure light at this time, then you can see actual oil pressure as the engine warms up and reaches operating temperatures, if the oil pressure is actually low then you could have internal bearings that have excessive clearances allowing too much oil pressure to escape, if you have good oil pressure then you may have a faulty oil pressure sender. Or you could just take a chance and replace the oil pressure sender and see if that cures your low oil pressure light. HTH
