Power Steering Pressure Switch

On 2.5L with power steering, a power steering pressure switch is used. The switch is located on power steering pressure line, next to power steering pump. Power steering pressure switch sends a signal to PCM when system pressure rises to greater than 250-300 psi (17.6-21.1 kg/cm² ). When power steering load is high, PCM, through Idle Air Control (IAC) motor, will increase engine idle speed to prevent stalling.
