Standard Ignition SC671 Vehicle Speed Sensor

Vehicle Speed Sensor for Ford Applications

Standard Ignition SC671 is a vehicle speed sensor built for direct-fit service on select Ford models, including EcoSport, Fiesta, and Courier applications. It uses OE-match connectors and terminals to support proper fit and an accurate output signal for consistent speedometer and drivetrain performance.

Key Features

• OE-match connectors and terminals for proper electrical fit
• OE-match output signal for accurate speed readings
• Female connector with triangle shape and plug-in design
• 3-pin male terminals for transmission-mounted installation
• 100% environmental, endurance, and end-of-line tested for signal amplitude and polarity
• Precision-manufactured components support engine performance and gas and exhaust regulation

Detailed Description

Standard Ignition SC671 is a transmission-mounted vehicle speed sensor designed for Ford vehicles that rely on a precise speed signal for drivability and instrument operation. It is a direct replacement for applications such as 2004-2012 Ford EcoSport with speedometer cable, 2003-2009 Ford Fiesta, 2001 Ford Fiesta, and 2002-2006 Ford Courier. This part number, SC671, is engineered with OE-style connectors, a female plug-in interface, and a 3-pin terminal layout to help maintain correct signal transfer in the vehicle’s electrical system. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Resolve

• Inaccurate or erratic speedometer readings
• Loss of vehicle speed signal to the control system
• Transmission-related drivability concerns tied to speed input
• Check engine conditions related to speed sensor output
• Improper signal amplitude or polarity at the sensor connection

Installation Notes and Tips

Install SC671 on the transmission using the bolt-mount location specified for the application. Confirm the connector shape, terminal count, and plug-in style match the original sensor before installation. Verify the vehicle application carefully for Ford EcoSport, Ford Fiesta, or Ford Courier fitment, since year coverage varies by model. The part number SC671 should be matched to the original sensor location and connector style before final assembly.

Quality Assurance

Standard Ignition tests this vehicle speed sensor for environmental exposure, endurance, and end-of-line signal performance, including amplitude and polarity checks. Those validation steps help support consistent operation in Ford speed sensor applications.
