Delphi SS21646 ABS Wheel Speed Sensor - Front Left

Delphi ABS Wheel Speed Sensor SS21646

Delphi SS21646 is a front left ABS wheel speed sensor built for vehicles that rely on accurate wheel-speed input for anti-lock braking and stability system operation. It is a direct-fit replacement for select Toyota, Scion, and Lexus applications, including Toyota Mirai, Toyota Corolla iM, Toyota Prius V, Scion iM, Scion tC, Scion xB, and Lexus HS250h.

With OE-calibrated testing and a vehicle-specific wiring harness, this Delphi ABS wheel speed sensor supports consistent signal output at the front left wheel. The SS21646 is a practical choice for drivers and repair shops servicing ABS warning light concerns on covered Toyota Prius V and Scion xB applications.

Key Features

• Front left ABS wheel speed sensor for select Toyota, Scion, and Lexus vehicles
• OE-standard testing and calibration for accurate wheel-speed readings
• Wiring harness included for a direct replacement-style installation
• Black connector with square shape, male connector and male terminals
• 2-terminal design with 1 connector
• Wiring harness length: 1021 mm (39.819 in.)
• Package contents: ABS wheel speed sensor and instruction sheet
• Delphi part number SS21646

Detailed Description

Delphi SS21646 is engineered as an ABS wheel speed sensor for the front left position, where it monitors wheel rotation and sends the signal needed by the ABS control system. Delphi validates its sensors to OE standards, helping maintain accurate readings across the covered applications. This part number is a fitment match for vehicles such as the Toyota Mirai, Toyota Corolla iM, Toyota Prius V, Scion iM, Scion tC, Scion xB, and Lexus HS250h, making it a focused replacement for front-left sensor service. If you are replacing a failed Toyota Prius V ABS sensor or a Scion xB wheel speed sensor, SS21646 provides the correct position-specific configuration.

This part cross-references Standard Ignition ALS2109 for the same application.

What It Helps Address

• ABS warning light triggered by a failed front left wheel speed sensor
• Loss of wheel-speed signal to the ABS module
• Erratic anti-lock brake system operation caused by sensor signal issues
• Stability or traction control faults tied to wheel-speed input
• Intermittent braking system fault codes related to the front left sensor circuit

Installation Notes and Tips

Verify the front left position before installation and compare the connector, terminal count, and harness length to the original sensor. Inspect the tone ring, hub area, and wiring path for damage or contamination before installing the new sensor. Clear stored ABS codes after installation and confirm proper system operation with a road test and scan tool verification.

Quality Assurance

Delphi backs this sensor with OE development and product validation methods. Each sensor is tested and calibrated to OE standards to support accurate readings and reduce repeat repairs. Delphi SS21646 is built for dependable replacement service in the specified front left applications.
