Airtex 1P2311 ABS Wheel Speed Sensor

The Airtex 1P2311 is a direct-fit replacement ABS wheel speed sensor engineered to restore proper anti-lock braking system function. Airtex designed this sensor as a better-than-OE replacement, addressing the primary cause of wheel speed sensor failure—environmental damage—through enhanced construction and protective materials.

Key Features:

• Direct OE Replacement: Matches original mounting configuration, connector design, and wire length for a straightforward, plug-and-play installation
• Heavy-Duty Wire Insulation: Upgraded harness sheathing resists impact- and corrosion-related damage that commonly degrades OE sensors
• Weather-Pack Connector: Sealed connector design locks out dirt, moisture, chemicals, and other contaminants that can cause premature failure
• Complete Installation Kit: Includes mounting hardware, grease (as appropriate), and detailed installation instructions

The ABS wheel speed sensor monitors wheel rotation speed and transmits that data to the ABS control module, which uses it to modulate brake pressure and prevent wheel lockup. A failed sensor can trigger the ABS warning light, cause erratic braking behavior, and disable traction or stability control systems. The Airtex 1P2311 is built to deliver reliable, long-term performance as a lasting solution—not just a temporary fix.
