This is not a sending unit.  It is a pressure activated switch that closes
for continuity when power steering hydraulic system pressure reaches the set
point of the switch.  Continuity through the switch allows the ECU to up the
base (curb) idle speed of the engine to overcome the power steering pump
resistance at full pressure output.  This keeps your engine from dying while
maneuvering in parking areas, etc. with the engine at or near curb idle
speed.
