What It Helps Address

• ABS warning light caused by a failed front wheel speed sensor
• Erratic or missing wheel speed signal data
• ABS system faults related to front sensor circuit issues
• Traction control or stability system faults tied to wheel speed input
• Intermittent braking system fault codes from sensor degradation

Installation Notes and Tips

Verify connector shape, terminal count, and front position before installation. The sensor uses a square male connector with blade terminals and includes a wiring harness. Inspect the mounting location and surrounding tone ring or hub area for damage, corrosion, or debris before final assembly. Confirm the vehicle application by year, make, model, and front position for Buick Encore and Chevrolet Trax service.
