Standard Ignition Power Steering Pressure Switch P/N:PSS45
Keep your engine's idle control informed of steering load with the Standard Ignition Power Steering Pressure Switch (PSS4). This switch senses high-pressure conditions in the power steering system — such as low-speed parking maneuvers — and signals the engine management system so it can adjust idle and compensate for the added pump load. It's a direct-fit replacement across a wide range of Ford, Lincoln, Mazda and Mercury applications, including the Ford Explorer, F-150, Ranger, Mustang, Taurus and E-Series vans, the Lincoln Town Car and LS, the Mazda B2300, and the Mercury Sable and Mountaineer. See the Buyer's Guide tab for the full year-by-year list.
