OE-Style Sensor Construction

Delphi sensors are developed and validated using OE-focused methods, with calibration to OE standards for accurate readings. That matters for ABS systems that depend on consistent wheel speed data to manage braking response and traction control. This SS20751 rear sensor is a direct-fit style replacement for many BMW rear axle applications, including 2012-2020 BMW 320i, 328i, 330i, 430i, 440i, M240i, and related xDrive and Gran Coupe models.

This part cross-references Standard Ignition ALS2724 for the same application.

• Loss of consistent ABS feedback during braking events

Installation Notes

Verify rear-position application before installation and compare the connector, terminal count, and sensor shape to the original part. Inspect the harness routing and mounting points for damage, and confirm the tone ring or wheel speed target is clean and free of debris before final assembly. The package includes the sensor and instruction sheet only; mounting hardware is not included.
