Compatible with 2018-2022 Toyota C-HR, front. This part cross-references Standard Ignition ALS3513 for the same application.

For Toyota C-HR front ABS wheel speed sensor replacement, SS21540 is a direct-fit service part for the listed model years. It is built to deliver the wheel-speed data the ABS control system uses to monitor braking performance and traction-related functions.

What It Helps Address

• ABS warning light caused by a failed front wheel speed sensor
• Erratic or missing wheel-speed signal data
• Traction control or stability system fault codes tied to the front sensor
• Brake system communication issues related to sensor signal loss
• Intermittent drivability concerns traced to wheel-speed input errors

Installation Notes

Verify connector style, harness length, and front position before installation. Inspect the tone ring, hub area, and wiring path for damage or corrosion that could affect signal quality. Follow the included instruction sheet and confirm all electrical connections are fully seated after installation.

Quality Assurance

Delphi sensors are developed and validated using OE-focused methods and calibrated to OE standards to help maintain accurate readings and reduce repeat repairs.
