If your good with electrical, this might help you out.
OPERATION
The switch provides an input to the PCM during periods of high pump load and low engine RPM; such as during parking maneuvers.
When power steering pump pressure exceeds 2758 kPa (400 psi) , the switch is open. The PCM increases idle air flow through the IAC motor to prevent engine stalling. The PCM sends 12 volts through a resister to the sensor circuit to ground. When pump pressure is low, the switch is closed.
sounds like something I can do!!! I am electrical handy

I'll work with my mechanic (we are good friends) and I will test the switch.

So I am guessing, no 12v reading... bad switch.?
