Standard Ignition SC629 Vehicle Speed Sensor

Vehicle Speed Sensor for Chevrolet Spark

Standard Ignition SC629 is a vehicle speed sensor for select Chevrolet Spark models from 2014-2022. It uses OE-match connectors and terminals to support proper fit and delivers an output signal calibrated for accurate speed readings and consistent drivability.

Key Features

• OE-match connector and terminal design for proper electrical fit
• OE-match output signal for accurate vehicle speed data
• 100% environmental, endurance, and end-of-line tested
• Signal amplitude and polarity verified for consistent performance
• Precision-manufactured components support engine performance and emissions control
• Female oval plug-in connector with bolt-mount installation
• 3-pin male terminals for transmission-mounted applications

Detailed Description

Standard Ignition SC629 is a transmission-mounted vehicle speed sensor built for Chevrolet Spark applications. It is engineered with OE-style connectors and terminals, an oval plug-in connector, and a bolt-mount design to match the original electrical interface and mounting style. The sensor’s output signal is calibrated to provide accurate speed information to the vehicle control system, helping maintain proper engine operation and speed-related system performance. This part cross-references Standard Motor Products (e.g., SN8331, VSS1163) for the same application.

Compatible With 2014-2022 Chevrolet Spark. Use Standard Ignition SC629 when replacing a worn or faulty vehicle speed sensor on Spark models that require a transmission-mounted, 3-pin sensor with an oval female connector. The part number SC629 is also a useful reference when verifying the correct replacement during service.

What It Helps Solve

• Inaccurate speedometer readings
• Erratic transmission or shift behavior tied to vehicle speed input
• Check engine lights related to speed sensor signal faults
• Intermittent speed signal loss from a failing sensor
• Driveability issues caused by incorrect speed data

Installation Notes and Tips

Install on the transmission at the original sensor location and confirm the connector shape, terminal count, and mounting style before replacement. Inspect the harness and connector terminals for corrosion, bent pins, or damaged locking features before installing SC629. After installation, clear any stored fault codes and verify speed signal operation during a road test.

Quality Assurance

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