Q: low oil pressure light Cad Northstar engine on 2005 Cadillac DeVille

Edit
Low oil pressure light comes on intermittently and "stop engine" also. Oil level is ok & engine heat guage never rises above "normal". Can the sensor be bad & where is it located?

I would initially change the oil and filter and sender unit and see if the light goes out if it doesn't I would screw in a mechanical gauge and verify actual pressure. Oil pressure switch is on the engine block near the oil filter I think, has two wires attached to it, tan/black, black/white. Oil pressure should be 5 psi @idle and 35 at 2000 RPM.
