Power Steering Pressure Switch: Description and Operation

POWER STEERING OIL PRESSURE SWITCH

Component Description

The power steering oil pressure switch is attached to the power steering high-pressure tube 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.
