Standard Ignition ALH138 ABS Wheel Speed Sensor Wiring Harness - Front Right

ABS Wheel Speed Sensor Harness for Toyota

Standard Ignition ALH138 is an ABS wheel speed sensor wiring harness for front right applications on select Toyota trucks and SUVs. It connects the antilock brake speed sensor circuit with the correct female and male blade-and-pin terminals for a direct-fit repair on the front right corner.

Compatible with 2007-2019 Toyota Sequoia, front right, and 2007-2019 Toyota Tundra, front right, this harness is built around the connector and terminal layout needed for a secure electrical connection. Standard Ignition ALH138 is a practical replacement when the original harness is damaged, corroded, or no longer maintaining a stable signal.

Detailed Description

This harness is used in the antilock brake system to carry the wheel speed sensor signal from the front right wheel area to the vehicle wiring. On Toyota Sequoia and Toyota Tundra applications, a worn or damaged harness can trigger ABS warning lights, intermittent wheel speed readings, or communication faults in the brake control system. Standard Ignition ALH138 restores the electrical path with the correct connector style and terminal configuration for the listed fitments.

This part cross-references Holstein 2ABS4843 for the same application. Standard Ignition ALH138 is also referenced by interchange numbers including 1P3552 and 536139.

What It Is Used For

• Repairing a broken ABS wheel speed sensor harness at the front right wheel
• Restoring wheel speed signal continuity in the antilock brake system
• Replacing corroded or heat-damaged sensor wiring on Toyota Sequoia and Toyota Tundra
• Addressing ABS warning lamp concerns caused by harness connection faults
• Correcting intermittent sensor readings from a compromised front right harness

Installation Notes and Tips

Verify connector shape, terminal style, and mounting points before installation. Inspect the sensor, connector terminals, and nearby wiring for corrosion, abrasion, or impact damage so the new harness is not installed over an unresolved fault. Confirm the front right routing matches the original harness path and secure the harness away from moving suspension components and heat sources.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and ignition components, and ALH138 is built to match the listed Toyota Sequoia and Toyota Tundra applications with the specified connector and terminal configuration.
