Power Steering Oil Pressure Switch: Description and Operation

The power steering oil pressure switch is attached to the power steering pump and detects a power steering load. When a power steering load is detected,
it signals the ECM. The ECM adjusts the IACV-AAC valve to increase the idle speed and adjust for the increased load.
