Delphi SS21438 ABS Wheel Speed Sensor - Front Left or Rear Left

Delphi ABS Wheel Speed Sensor SS21438

Delphi SS21438 is an ABS wheel speed sensor built for accurate wheel-speed signal input and OE-style fitment on select Toyota trucks and SUVs. It is a direct replacement option for front left and rear left applications on the listed Sequoia and Tundra models.

Key Features

• ABS wheel speed sensor for brake and stability system signal monitoring
• OE-calibrated and tested to support accurate readings
• 1 rectangular female connector with 2 male terminals
• No mounting hardware included
• Package includes the ABS wheel speed sensor and instruction sheet
• Position-specific applications: front left and rear left

Detailed Description

Delphi SS21438 is engineered for vehicles that rely on precise wheel-speed data for ABS operation. Delphi validates its sensors to OE standards and calibrates them for consistent output, helping maintain reliable signal quality and reduce repeat repairs. This part number is used on 2018-2022 Toyota Sequoia, front left, and 2018-2021 Toyota Tundra, rear left. If you are searching for a Toyota Sequoia ABS wheel speed sensor or a Toyota Tundra rear left wheel speed sensor, SS21438 is the listed application.

This part cross-references Standard Ignition ALS3167 for the same application.

What It Helps Address

• ABS warning light caused by a failed wheel speed sensor
• Erratic or missing wheel-speed signal data
• ABS, traction control, or stability control faults tied to sensor input
• Intermittent brake system warning messages related to the affected wheel position

Installation Notes

Verify the wheel position before ordering, since SS21438 is listed for front left on Toyota Sequoia and rear left on Toyota Tundra. Confirm connector style, terminal count, and sensor length against the original part before installation. The sensor uses a rectangular female connector, 2 male terminals, and does not include mounting hardware or a wiring harness.

Quality Assurance

Delphi backs its sensor portfolio with OE development and product validation methods. SS21438 is tested and calibrated to OE standards to support accurate wheel-speed readings on the specified Toyota applications.
