Power Steering Pressure Switch:
POWER STEERING PRESSURE SWITCH-PCM INPUT
A pressure sensing switch is located on the power steering gear.
The switch provides an input to the PCM during periods of high pump load and low engine RPM; such as during parking maneuvers.
When power steering pump pressure exceeds 4137 kPa (600 psi), the switch is open. The PCM increases idle air flow through the IAC motor to prevent engine stalling. When pump pressure is low, the switch is closed.
