Standard Ignition SC117 Vehicle Speed Sensor

Vehicle Speed Sensor for Ford and Mercury

Standard Ignition SC117 is a transmission-mounted vehicle speed sensor built for direct-fit service on select Ford and Mercury applications. It uses a 3-pin male terminal layout with a female triangle connector and screw-in mounting for a secure electrical and mechanical connection.

Key Features

• Vehicle speed sensor for transmission-mounted applications
• Female connector with triangle shape and plug-in design
• 3-pin male terminal configuration
• Screw-in mounting type for trans mount installation
• Built by Standard Ignition with controlled manufacturing from component to finished part
• Coverage for domestic and import service applications

Detailed Description

Standard Ignition SC117 is engineered for accurate speed signal delivery in vehicles that rely on a transmission-mounted sensor. It is listed for 1995 Ford Contour, 1996-2000 Ford Contour, 1998-2001 Ford Fiesta, 1995 Mercury Mystique, 1996-2000 Mercury Mystique, and 1999-2002 Mercury Cougar. If you are replacing a worn Ford Contour vehicle speed sensor or servicing a Mercury Mystique or Mercury Cougar transmission speed sensor, SC117 provides the connector and mounting style needed for a proper OE-style replacement. This part cross-references Dorman OE Solutions 917-639 for the same application.

What It Helps Fix

• Erratic or inaccurate speedometer readings
• Transmission shift concerns related to vehicle speed input
• Check engine lights triggered by speed sensor faults
• Intermittent speed signal loss from a damaged sensor
• Drivability issues caused by poor transmission speed data

Installation Notes and Tips

Confirm the connector shape, terminal count, and transmission mount location before installation. SC117 uses a screw-in mounting style and a plug-in female connector with 3 male pins, so matching the original sensor configuration is important for proper fitment. Verify the vehicle application by year, make, and model before ordering.
