Standard Ignition Power Steering Pressure Switch P/N:PSS3
Keep the PCM informed of high-demand steering moments with the Standard Ignition Power Steering Pressure Switch, PN PSS73. It installs as a direct-fit replacement for the 2000-2003 Ford Windstar, monitoring hydraulic pressure in the power steering system and signaling the vehicle's computer when that pressure exceeds the normal operating range so the engine management can respond to the added load.
If a failed pressure switch is the cause of an unstable idle during hard steering or a related steering-load fault code, this switch replaces the original. Always diagnose the underlying cause before replacing.
Interchange: PS1578 · PS365 · XF2Z3N824AA
