Hi Brian, thank you for reaching out. No, the ABS sensor itself is not included with this assembly. This knuckle does include the provisions for ABS functionality, as it comes with the wheel hub and bearing assembly integrated, which typically incorporates the ABS tone ring needed for the sensor to function properly. The ABS sensor must be transferred from your existing assembly or purchased separately. Some users have noted that reusing the original ABS sensor is necessary when installing this part.
