Delphi SS21795 ABS Wheel Speed Sensor - Front Left

Overview

Delphi SS21795 is an ABS wheel speed sensor for select Subaru applications with front left fitment. It is built with OE development and validation methods, and the sensor is tested and calibrated to OE standards for accurate signal output.

Key Features

• ABS wheel speed sensor for brake system speed monitoring
• OE-standard testing and calibration for consistent readings
• 31.98 in. wiring harness length for the listed application
• Gray connector with rectangular, 1-connector design
• Male pin terminals with wiring harness included
• Package contents include the sensor and instruction sheet

Detailed Description

This Delphi ABS wheel speed sensor, part number SS21795, is engineered for vehicles that rely on precise wheel speed input to support ABS operation. The front left application coverage includes 2014-2018 Subaru Forester, 2016-2017 Subaru Crosstrek, 2013-2016 Subaru Impreza, and 2013-2015 Subaru XV Crosstrek. Delphi SS21795 uses a gray rectangular connector, male pin terminals, and a wiring harness length of 31.98 inches (820 mm) to match the listed fitment requirements.

Delphi’s sensor portfolio is developed with OE-focused validation and calibration practices. That approach helps deliver accurate readings and reduces the chance of repeat repairs. If you are replacing a worn or faulty Subaru ABS wheel speed sensor, SS21795 provides a direct-fit service part for the specified front left position.

This part cross-references Standard Ignition ALS2520 for the same application.

What It Is Used For

• Restoring ABS wheel speed signal output
• Replacing a damaged or contaminated sensor
• Addressing ABS warning light concerns tied to wheel speed input
• Correcting intermittent or inaccurate speed signal readings
• Servicing front left sensor applications on listed Subaru models

Installation Notes and Tips

Verify connector shape, terminal count, and harness length before installation. Confirm the front left position and compare the old sensor to the new unit before removal. Follow the vehicle service procedure for routing and securing the harness to avoid strain or abrasion.

Quality Assurance

Delphi tests and calibrates its sensors to OE standards and uses stringent development and validation methods. Part number SS21795 is supported by that OE-focused manufacturing process.
