Standard Ignition Power Steering Pressure Switch P/N:PSS74
Standard Motor Products
Keep your engine management informed when steering effort climbs with the Standard Ignition Power Steering Pressure Switch, part number PSS43. It senses pressure in the power steering system and sends a signal the vehicle uses to compensate for the added load, such as at idle. It fits many vehicles, among them the 2006-2012 Ford Fusion, 2006-2009 Mercury Milan and 2002-2005 Ford Thunderbird, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list.
Signs this part may need replacing: A failing power steering pressure switch may cause the engine to stumble, idle roughly or stall when the wheel is turned at low speed. Fluid seeping at the switch is another sign. These symptoms can have other causes, so diagnose the problem before replacing the switch. If the switch is the cause, the PSS43 replaces it.
