Delphi SS21378 ABS Wheel Speed Sensor - Front Left

Delphi ABS Wheel Speed Sensor SS21378

Delphi SS21378 is a front left ABS wheel speed sensor built for direct replacement on select Hyundai and Kia vehicles. It provides the signal the ABS system uses to monitor wheel speed, helping maintain consistent braking system input on the applications listed below.

Key Features

• Front left ABS wheel speed sensor
• 1 rectangular male connector with 4 female terminals
• Length: 51.06
• Package contents: ABS wheel speed sensor and instruction sheet
• No mounting hardware included
• No wiring harness included

Application Details

Compatible with 2019 Hyundai Santa Fe XL, front left; 2013-2018 Hyundai Santa Fe, front left; 2013-2018 Hyundai Santa Fe Sport, front left; and 2014-2015 Kia Sorento, front left. This Delphi ABS wheel speed sensor SS21378 is a fitment-specific replacement for the listed vehicles and position.

Delphi validates its sensor lineup to OE standards and calibrates each unit for accurate readings. That OE-focused testing helps support reliable wheel speed input for the ABS system and reduces repeat repairs on the covered Hyundai Santa Fe, Hyundai Santa Fe Sport, Hyundai Santa Fe XL, and Kia Sorento applications.

This part cross-references Standard Ignition ALS2537 for the same application.

What It Helps Address

• ABS warning light caused by a failed front left wheel speed sensor
• Erratic or missing wheel speed signal at the front left wheel
• ABS system fault codes related to wheel speed input
• Brake control issues tied to inaccurate sensor readings
• Repeat repairs from a sensor that does not meet OE-style calibration needs

Installation Notes

Verify the connector style, terminal count, and front left position before installation. Compare the original sensor length and mounting points to the Delphi SS21378, and inspect the tone ring, hub area, and wiring path for damage or contamination before final assembly. Because mounting hardware and wiring harness are not included, reuse or source the required vehicle-specific components as needed.

Quality Assurance

Delphi backs this sensor with OE development and product validation methods, and each unit is tested and calibrated to OE standards for accurate signal output. That focus on validation supports dependable performance on the listed Hyundai and Kia fitments, including Hyundai Santa Fe and Kia Sorento applications.
