Detailed Description

Standard Ignition ALS3319 is engineered for vehicles that rely on accurate wheel speed data for ABS operation. On the Cadillac XT4, the front left sensor monitors wheel rotation and sends the signal needed by the braking and traction control systems. The sensor mounts at the spindle with one bolt hole and a direct, snap-fit design, helping maintain the original routing and connection style. If you are replacing a failed front left ABS wheel speed sensor on a 2019, 2020, 2021, 2022, 2023, or 2024 Cadillac XT4, ALS3319 provides the correct application match.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• ABS warning light caused by a faulty front left wheel speed sensor
• Erratic or missing wheel speed signal at the spindle
• Traction control or stability control faults tied to wheel speed input
• Brake system diagnostic trouble codes related to the front left sensor
• Intermittent sensor connection from a damaged harness or connector

Installation Notes and Tips

Verify the front left position before installation and compare the connector, terminal style, and harness length to the original part. Inspect the spindle mounting point and wiring path for corrosion, abrasion, or debris before securing the new sensor. Confirm that the connector seats fully and that the harness is routed away from moving suspension components.

Quality Assurance

Standard Ignition manufactures replacement electrical and sensor components for automotive service applications. ALS3319 is built to match the listed fitment for the Cadillac XT4 and to support proper ABS wheel speed signal replacement at the front left position.
