Power Steering Pressure Switch: Description and Operation
This switch informs the PCM when the power steering pressure is high. During high pressure conditions, the Powertrain Control Module (PCM) will
increase idle speed to compensate for the additional load. When the switch closes, the PCM will increase idle speed to compensate for the additional
load.
