Power Steering Pressure Switch: Description and Operation
Pressure Switch
When hydraulic pressure reaches 3430 kPa (500 psi), the pressure switch closes causing the Engine Control Module (ECM) to actuate the idle air
control valve, which increases the engine rpm to prevent the overload-induced engine speed slow down. The switch opens when hydraulic pressure
drops to 2940 kPa (430 psi).
