Power Steering Oil Pressure Switch: Description and Operation
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.
