Detailed Description

Delphi SS21434 is built as a rear ABS wheel speed sensor for vehicles that need accurate wheel rotation data sent to the anti-lock brake system. Delphi validates its sensor lineup to OE standards and calibrates each unit for consistent readings, helping maintain proper brake system performance and reducing repeat repairs. This part cross-references Standard Ignition ALS2379 for the same application.

For shoppers searching for a rear ABS wheel speed sensor for Ford Focus, Ford Escape, Ford C-Max, or Lincoln MKC, SS21434 provides a direct replacement option with the correct connector style and terminal layout. The Delphi SS21434 is a practical choice when replacing a failed rear wheel speed sensor on these applications.

What It Helps Solve

• ABS warning light caused by a failed rear wheel speed sensor
• Wheel speed signal loss at the rear axle
• Erratic anti-lock brake system operation
• Traction control or stability system fault codes tied to wheel speed input
• Intermittent brake system alerts from damaged sensor wiring or internal sensor failure

Installation Notes and Tips

Verify rear position, connector shape, and terminal count before installation. Inspect the tone ring, hub area, and wiring connector for corrosion or damage before installing the new sensor. Use the included instruction sheet during replacement and confirm the sensor is fully seated and routed away from moving suspension components.

Quality Assurance

Delphi sensors are developed and validated using OE-focused methods and tested to OE standards for accurate readings. That calibration focus supports consistent brake system input and helps reduce comebacks after repair.
