Delphi ABS Wheel Speed Sensor SS21172

Delphi SS21172 is an ABS wheel speed sensor built for front axle applications on select BMW models. It uses a black oval connector, a 2-pin male terminal design, and an included wiring harness to support a direct electrical connection at the wheel end.

For BMW 528i, 535i, 550i, 740i, 750i, and related front-position applications, this sensor is calibrated to OE standards to deliver accurate wheel speed readings. Delphi SS21172 is a practical replacement when the original ABS sensor is damaged, intermittent, or no longer reporting correctly.

Key Features

  • ABS wheel speed sensor for front, front left, and front right positions, depending on vehicle application
  • Black connector with oval shape and 1 connector interface
  • 2-terminal male pin configuration
  • Wiring harness included with 33.93 in. / 870 mm length
  • Package contents: ABS wheel speed sensor and instruction sheet
  • OE-standard testing and calibration for accurate signal output

Detailed Description

Delphi SS21172 is part of Delphiโ€™s sensor lineup for vehicle speed and braking systems. The sensor is validated through OE development methods and calibrated to OE standards, helping maintain consistent wheel speed data for the ABS control system. That accuracy matters on BMW 535i GT, BMW 640i Gran Coupe, BMW 650i Gran Coupe, and other listed applications where the ABS module depends on clean input from the wheel sensor.

This part cross-references Standard Ignition ALS2722 for the same application. It also cross-references 5S12710 and 34 52 6 853 859 for select applications.

What It Helps Address

  • ABS warning light caused by a failed front wheel speed sensor
  • Erratic or missing wheel speed signal at the ABS module
  • Traction control or stability control faults tied to wheel speed input
  • Brake system fault codes related to front axle sensor performance
  • Intermittent sensor readings from a damaged harness or connector

Installation Notes and Tips

Verify the exact position before ordering, since SS21172 is listed for front, front left, and front right applications depending on the BMW model. Confirm connector style, harness routing, and mounting points against the original sensor before installation. Inspect the wheel hub area, tone ring, and wiring path for damage or contamination that could affect the new sensor signal.

Quality Assurance

Delphi tests and calibrates its sensors to OE standards and uses stringent product validation methods during development. That process supports accurate readings and helps reduce repeat repairs on BMW ABS wheel speed sensor replacements.
