Power Steering Pressure Switch

Power steering pressure switch sends a signal to Engine Control Module/Powertrain Control Module (ECM/PCM) when power steering pressure (load) rises to more than a predetermined pressure. When power steering load is high, such as during parking, ECM/PCM increases engine idle speed through IAC motor to prevent stalling. The switch is located on the side of the power steering pump.
