Help your engine compensate for steering load at idle with the Standard Ignition Power Steering Pressure Switch PSS55, a direct-fit OE replacement Fusion switch for the 2011 Ford Fusion that also fits the 2007-2009 Lincoln MKZ. The switch monitors pressure in the power steering system and signals the engine control system when steering load rises, such as during low-speed parking maneuvers, so idle speed can be adjusted. See the Buyer's Guide tab for engine details.
Signs this switch may need replacing include the idle dipping or the engine stalling when the steering wheel is turned at low speed, a check engine light, or power steering fluid seeping at the switch. Other faults can cause these symptoms, so diagnose the cause before replacing any parts. If a failed pressure switch is the cause, PSS55 replaces it.
