Detailed Description

Delphi SS12406 is a vehicle speed sensor used to monitor transmission or drivetrain speed data and send that information to the vehicle control system. This part number is listed for applications including Chevrolet Blazer, Chevrolet Malibu, GMC Acadia, Buick Enclave, Buick Envision, Buick Regal Sportback, Cadillac XT4, Chevrolet Equinox, Chevrolet Traverse, GMC Terrain, and Buick LaCrosse. If you are replacing a worn or failing sensor on a Chevrolet Malibu or GMC Terrain, SS12406 provides an OE-style service solution with the connector and harness configuration needed for the listed applications.

Delphi’s sensor portfolio is developed and validated to OE standards, and this part follows that approach with tested calibration for accurate readings. The result is a replacement vehicle speed sensor that supports proper signal delivery in vehicles such as the Chevrolet Equinox and Buick Enclave, where speed data is used by the control modules and related systems.

What It Helps Resolve

• Erratic or inaccurate vehicle speed readings
• Speedometer operation problems caused by a failing sensor
• Transmission shift concerns related to incorrect speed input
• Diagnostic trouble codes tied to vehicle speed sensor performance
• Intermittent signal loss from a damaged sensor or connector

Installation Notes and Tips

Verify connector style, terminal count, and harness length before installation. SS12406 uses a green rectangular male connector with two male blade terminals and an included wiring harness, so matching the original configuration is important for proper installation. Confirm the vehicle application by year, make, and model before ordering, especially on Chevrolet Malibu, Chevrolet Blazer, and GMC Acadia listings.

Quality Assurance

Delphi validates its sensors through OE development methods and product testing, with calibration to OE standards to support accurate readings and reduce comebacks. This part number is SS12406.
