Delphi SS21421 ABS Wheel Speed Sensor - Front Right

Delphi ABS Wheel Speed Sensor SS21421

Delphi SS21421 is a front right ABS wheel speed sensor built for direct replacement on select Toyota applications. It uses a standard replacement design with a pre-attached wiring harness and a 2-terminal female connector to support accurate wheel speed signal delivery for ABS operation.

Compatible with 2019-2024 Toyota RAV4, 2021-2024 Toyota RAV4 Prime, and 2021-2024 Toyota Venza, this Delphi ABS wheel speed sensor is a fitment-specific solution for front right service on these vehicles. The SS21421 is calibrated to OE standards to help maintain consistent readings and reduce repeat repairs.

Key Features

• Front right ABS wheel speed sensor for select Toyota models
• Standard replacement design for direct service applications
• Pre-installed wiring harness with 1281 length
• Black oval female connector with 2 blade terminals
• OE-standard testing and calibration for accurate signal output
• Package contents: ABS wheel speed sensor and instruction sheet

Detailed Description

Delphi SS21421 is engineered for vehicles that rely on precise wheel speed input to the ABS control system. By monitoring wheel rotation at the front right position, the sensor helps the system interpret braking conditions and respond appropriately during hard stops, slippery surfaces, or uneven traction events. This part cross-references Monroe Shocks & Struts (e.g., 89542-42070, 533903) for the same application.

Delphi’s sensor portfolio is developed and validated to OE standards, and this ABS wheel speed sensor follows that approach with calibrated output and application-specific fitment. It is a strong match for Toyota RAV4, Toyota RAV4 Prime, and Toyota Venza front right service where the original sensor has failed or is producing erratic readings. The part number SS21421 is also useful when searching for a direct OE-style replacement by application.

What It Helps Fix

• ABS warning light caused by a failed front right wheel speed sensor
• Erratic or missing wheel speed signal data
• ABS activation issues related to sensor output loss
• Brake system fault codes tied to the front right sensor circuit
• Intermittent braking control concerns from damaged sensor wiring or connector wear

Installation Notes and Tips

Verify the front right position before installation and compare the connector style, terminal count, and harness routing to the original part. Inspect the wheel hub area, tone ring, and nearby wiring for damage or contamination before installing the new sensor. After replacement, clear any stored ABS codes and confirm proper system operation with a scan tool if required.

Quality Assurance

Delphi tests and calibrates its sensors to OE standards to support accurate readings and consistent performance. The SS21421 is backed by Delphi’s OE-focused development and validation process for dependable replacement on the listed Toyota applications.
