Airtex 5S6827 ABS Wheel Speed Sensor

The Airtex 5S6827 is a direct-fit replacement ABS wheel speed sensor engineered to meet or exceed original equipment performance. Designed to address the leading cause of wheel speed sensor failure—environmental damage—this sensor incorporates heavy-duty construction enhancements that go beyond what many OE and standard replacement units offer.

Key Features:

• Weather-pack connectors that seal out dirt, moisture, chemicals, and other contaminants for long-term reliability
• Heavy-duty wire insulation and harness sheathing to resist impact- and corrosion-related damage
• Direct OE-replacement fit — matches original mounting design, connector type, and wire length for fast, straightforward installation
• Includes mounting hardware, grease packet, and detailed installation instructions so everything needed for the job is in the box

The Airtex 5S6827 is also sold under cross-reference number ALS664. This sensor monitors wheel rotational speed and transmits data to the ABS control module, which modulates brake pressure at each wheel to prevent lockup and maintain vehicle stability. A faulty wheel speed sensor can trigger the ABS warning light and compromise braking performance—restoring it with a quality replacement is essential for safe, reliable operation.
