Power Steering Pressure Switch for Ford and Lincoln

Standard Ignition PSS44 is a screw-in power steering pressure switch built for vehicles that rely on accurate steering-system pressure feedback. It uses a black housing with a female connector, male blade terminals, and a metal/plastic finish for a direct-fit replacement on select Ford, Lincoln, and Mercury applications.

Key Features

• Power steering pressure switch for engine management input
• Screw-in mounting type for the specified applications
• Black housing with female connector and male blade terminals
• 2-terminal design for reliable electrical connection
• Manufactured with specialized seals for durability in harsh engine conditions
• 100% pressure tested and end-of-line tested for linearity specifications

Detailed Description

Standard Ignition PSS44 is engineered to monitor power steering pressure and send the signal needed by the vehicle’s control system. On applications such as the Ford Crown Victoria, Mercury Grand Marquis, and Lincoln Town Car, accurate switch operation helps the engine management system respond properly when steering load changes. This part number, PSS44, is also listed for the 2000-2003 Ford Focus with a 3/8 Inch x 24 Thread note.

This part cross-references VEMO V25-73-0077 for the same application.
