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.
