Delphi SS21811 ABS Wheel Speed Sensor - Front Right

ABS Wheel Speed Sensor Overview

This Delphi ABS wheel speed sensor is built for precise wheel-speed signal delivery and OE-style validation. It fits Subaru Forester and Subaru Crosstrek applications with front right placement, and the SS21811 part number is a direct reference for matching the correct sensor.

Key Features

• OE-tested and calibrated for accurate readings.
• Includes a wiring harness for a complete sensor assembly.
• Gray connector with a rectangular female connector design.
• 2-terminal pin connection for secure electrical interface.
• Front right position fitment for confirmed Subaru applications.

Detailed Description

Delphi SS21811 is an ABS wheel speed sensor engineered for vehicles that rely on consistent wheel-speed input for anti-lock brake system operation. The sensor uses a 31.2-inch wiring harness, a single connector, and a female rectangular connector layout with pin terminals. Delphi validates and calibrates its sensors to OE standards, which supports accurate signal output and helps reduce repeat repairs. This part number, SS21811, is listed for 2018-2023 Subaru Crosstrek and 2019-2024 Subaru Forester front right applications.

This part cross-references Dorman - OE Solutions 533-540 and Standard Ignition ALS3169 for the same application.

Common Issues This Sensor Can Address

• ABS warning light caused by a failed wheel speed sensor.
• Erratic or missing wheel-speed signal input.
• Brake system fault codes related to the front right sensor circuit.
• Intermittent traction control or stability system alerts tied to sensor output.

Installation Notes and Tips

Verify connector shape, terminal count, and harness length before installation. Confirm front right placement and match the part number SS21811 to the vehicle application before ordering. The package contents include the ABS wheel speed sensor and instruction sheet; mounting hardware is not listed as included.

Quality Assurance

Delphi states that its sensors are tested and calibrated to OE standards and developed using stringent OE validation methods. That process is intended to support accurate readings and consistent performance in brake system sensing applications.
