Standard Ignition PSS73 Power Steering Pressure Switch

Standard Ignition PSS73 Power Steering Pressure Switch

The Standard Ignition PSS73 power steering pressure switch monitors hydraulic load in the steering system and signals the PCM when pressure rises above normal. It is a direct-fit service part for 2000-2003 Ford Windstar applications with the brown switch configuration.

Key Features

• Fits 2000-2003 Ford Windstar, N/A
• Brown, gold, and silver finish details with a screw-in mounting design
• Female connector with 1 rectangular connector and 2 male blade terminals
• Built with high-quality internal components, including springs and diaphragms, for consistent switching action
• High-temperature housing helps the switch withstand demanding engine bay conditions
• Standard Ignition PSS73 is engineered for durable, repeatable pressure signaling to the PCM

Detailed Description

Standard Ignition PSS73 is a power steering pressure switch designed to report high steering-system demand to the vehicle computer when hydraulic pressure climbs during steering input. For Ford Windstar models from 2000 through 2003, this switch supports proper PCM response by providing a clear electrical signal through its 2-terminal blade connection and screw-in mounting style. The PSS73 uses durable materials and a heat-resistant housing to handle harsh underhood conditions while maintaining reliable operation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Can Help Address

• Power steering pressure signal faults stored in the PCM
• Erratic idle behavior during steering input
• Loss of steering-load input to the engine management system
• Warning lights related to steering pressure circuit concerns
• Intermittent switch operation caused by heat or wear

Installation Notes and Tips

Verify the connector style, terminal layout, and screw-in mounting before installation. Inspect the steering pressure circuit for damaged wiring, corrosion, or fluid contamination, and confirm the replacement matches the brown switch application used on the 2000-2003 Ford Windstar. The Standard Ignition PSS73 should be installed on a clean, properly sealed port to maintain accurate pressure signaling.

Quality Assurance

Standard Ignition manufactures this switch with durable components and high-temperature housing materials to meet the demands of professional service work. The PSS73 is built to provide consistent pressure-switch performance in normal engine bay conditions.
