Detailed Description

This Standard Ignition ALH56 harness is a direct-fit style replacement for the rear left ABS wheel speed sensor circuit on the listed Toyota Avalon, Toyota Camry, and Lexus ES350 applications. The 813 mm harness length and OE-style connector layout help maintain the original routing and connection points used by the vehicle’s antilock brake system. This part cross-references Beck/Arnley 084-4933 for the same application.

Use Standard Ignition ALH56 when the original harness is damaged, corroded, or no longer maintaining a stable sensor connection. It supports consistent wheel speed signal delivery, which is critical for ABS operation on Toyota Camry, Toyota Avalon, and Lexus ES350 rear left positions.

What It Helps Solve

• Broken or frayed ABS sensor wiring at the rear left wheel
• Intermittent ABS warning light caused by poor sensor connection
• Corrosion at the connector or terminal interface
• Signal loss from damaged harness routing near the wheel area
• Fault codes related to wheel speed sensor circuit interruption

Installation Notes and Tips

Verify rear left fitment by year, make, model, and Japan-built note where applicable before installation. Inspect the sensor connector, terminals, and nearby wiring for corrosion or damage before connecting the new harness. Confirm the harness follows the original routing path and is secured away from moving suspension or brake components.

Quality Assurance

Standard Ignition supplies replacement electrical components for automotive repair applications, and ALH56 is built to match the connector style, terminal type, and harness length needed for the listed vehicles.
