Review on 🔍 Enhanced Motorcraft SW1547B Engine Oil Pressure Sensor by Collin Donahue

Without replacement. Mid 90's rebuilt Fords that still have the sensor (pre 97 you can do this by shorting a resistor on the cluster for the oil sensor, after 96 the resistor is in the sensor) and it responds very well to RPM changes, high on starting and Depending on the engine, accelerating, mid or lower idle. Aftermarket devices just don't work properly or are slower to respond. The block is engraved with US patent 4079351 and is a great solution for an old engine. It's a shame Ford removed this as customers complain of the sensors moving. I think they wouldn't want this on engines like the 5.4 with VVT that suffer from low oil pressure.
