Delphi ABS Wheel Speed Sensor SS21106

Delphi SS21106 is an ABS wheel speed sensor built for rear axle applications that require accurate wheel speed input to the braking system. It is a direct-fit replacement for select Mercedes-Benz models, including rear right applications on the CLS550, CLS63 AMG, CLS63 AMG S, E300, E350, E550, and E63 AMG.

Key Features

• ABS wheel speed sensor for rear left or rear right positions, with vehicle-specific application guidance
• OE-calibrated and tested to support accurate wheel speed readings
• Black connector with rectangular 1-connector design
• 2-terminal male connector and male terminal configuration
• Wiring harness included for installation on the listed applications
• Delphi part number SS21106 for catalog and cross-reference lookup

Product Details

Delphi SS21106 is part of Delphi’s sensor portfolio, which is developed and validated using OE-focused methods. The sensor is calibrated to OE standards to help maintain consistent signal output from the wheel speed system, which is critical for ABS operation and related stability functions. This part cross-references Standard Ignition ALS2745 for the same application. For Mercedes-Benz owners searching for a rear wheel speed sensor for E350, E550, or E63 AMG applications, SS21106 provides a direct replacement option with the correct connector style and harness length.

What This Sensor Helps Address

• ABS warning light caused by a failed rear wheel speed sensor
• Erratic or missing wheel speed signal at the rear axle
• Brake system fault codes related to wheel speed input
• Intermittent traction control or stability control warnings
• Signal loss from a damaged sensor harness or connector
