Detailed Description
Standard ALS2039T is an ABS wheel speed sensor engineered for front-wheel applications on the Buick Enclave, Chevrolet Traverse, GMC Acadia, GMC Acadia Limited, and Saturn Outlook. The Hall-effect signal is calibrated to match OE output, which helps the ABS module read wheel speed accurately during braking and traction events. The sensor housing uses fiberglass-filled thermoplastic to better handle heat stress, while the FPM O-ring supports sealing at the mounting point. This part cross-references Monroe Shocks & Struts 71335 for the same application.
What It Helps Fix
- ABS warning light caused by a failing front wheel speed sensor
- Erratic or missing wheel speed signal to the ABS module
- Traction control or stability control faults tied to wheel speed input
- Brake system communication issues related to sensor signal loss
- Intermittent ABS operation from heat-damaged or leaking sensor components
Installation Notes and Tips
Verify the connector style, bolt-mount design, and front-position fitment before installation. Clean the mounting surface and inspect the tone ring or wheel hub area for damage or debris that could affect signal quality. Confirm the vehicle application by year, make, and model before replacing the sensor. Standard ALS2039T also interchanges with Standard Ignition ALS2039.
Quality Assurance
Standard maintains quality control throughout the manufacturing process to support consistent fit and signal performance. The sensor is built to OE-matching specifications for dependable operation in the listed front applications.
