Good morning, Roger.

In this particular instance the sensor was between the fuel pump and engine block. It looked like I would have to remove the fuel pump to get a wrench on it. The special socket did make it easy to remove the sensor. Oh, well.

Not sure they offer that info, though it could be a fun test to conduct someday.
Ford says that the 260 oil pressure = 35 – 55 psi.
The oil pressure sensor turns on at 3.0 - 8.3 psi.
(You have a problem if the oil pressure light comes on.)

The Falcon owner's manual says to check your oil level if the oil pressure light comes on. Ford thought that it was more likely that people would drive around with no oil than that their oil pumps would fail.
