Vehicle Speed Sensor for OE-Style Signal Accuracy

Standard Ignition SC637 is a vehicle speed sensor built for direct-fit replacement on select GM applications. It uses OE-match connectors and terminals to support proper fit, consistent signal output, and reliable transmission-mounted operation.

Key Features

  • Vehicle speed sensor for transmission-mounted applications
  • OE-match connector and terminal design for proper electrical fit
  • OE-match output signal for accurate speed readings and stable performance
  • Female oval plug-in connector with male pin terminals
  • Bolt-mount design with 3-terminal configuration
  • 100% environmental, endurance, and end-of-line testing for signal amplitude and polarity
  • Precision-manufactured components to support engine performance and gas and exhaust regulation

Detailed Description

Standard Ignition SC637 is engineered as a replacement vehicle speed sensor for 2013-2019 Cadillac ATS, 2016-2019 Chevrolet Camaro, 2014-2019 Chevrolet Corvette, and 2014-2016 Chevrolet Silverado 1500 applications. The sensor is mounted on the transmission and uses a female oval plug-in connector with male pin terminals for a direct electrical interface. Its OE-match output signal is intended to deliver accurate speed data to the vehicle control system, helping maintain consistent drivability and transmission operation. This part cross-references 5S13835 and 76626 for the same application.

What It Helps Address

  • Inaccurate vehicle speed readings on the dash or scan tool
  • Transmission shift concerns related to speed signal loss
  • Intermittent speedometer operation
  • Diagnostic trouble codes tied to vehicle speed sensor performance
  • Drivability issues caused by inconsistent speed input

Installation Notes and Tips

Verify the connector shape, terminal style, and transmission mounting location before installation. Confirm fitment for your specific Cadillac ATS, Chevrolet Camaro, Chevrolet Corvette, or Chevrolet Silverado 1500 by year and application details. Inspect the harness connector and mounting surface for damage or corrosion before connecting the new sensor.

Quality Assurance

Standard Ignition subjects this sensor to environmental, endurance, and end-of-line testing to verify signal amplitude and polarity. That testing process supports consistent output and dependable operation across the listed vehicle applications.
