Product Features and Specifications

The ALS522 ABS Wheel Speed Sensor features a bolt mount type with one bolt hole, designed to be installed directly on the spindle. It includes a female oval connector with one connector quantity and two male blade terminals, ensuring secure electrical connections. This sensor does not come with mounting hardware or a wiring harness, so these components must be sourced separately if needed. The absence of a dust shield means the sensor relies on the vehicle’s existing protection. The harness length is not included, as the sensor is supplied without wiring.

Purpose and Common Applications

This ABS wheel speed sensor is essential for monitoring wheel rotation speed, providing critical input to the anti-lock braking system and traction control. It is commonly used to address issues such as:

• ABS warning light activation due to faulty sensor signals
• Intermittent or no wheel speed readings affecting braking performance
• Traction control or stability control system malfunctions
• Uneven or erratic ABS braking behavior
• Diagnostic trouble codes related to wheel speed sensor faults

Installation Notes and Tips

Installation requires removing the old sensor from the spindle and securing the new sensor using the bolt mount with one bolt hole. Since mounting hardware and wiring harness are not included, ensure you have the correct bolt and wiring components before beginning installation. Handle the sensor carefully to avoid damaging the blade terminals or connector. Verify the connector gender and shape to ensure compatibility with your vehicle’s wiring harness.
