Airtex 5S7989 ABS Wheel Speed Sensor ALS204

The Airtex 5S7989 ABS wheel speed sensor (also called an ABS speed sensor or anti-lock brake sensor) is a replacement part for the anti-lock braking system. It monitors wheel rotation speed and sends that data to the ABS control module. The module uses the signal to adjust braking pressure at each wheel and help prevent wheel lock-up or loss of traction. The same signal can also feed speed-related vehicle functions.

Key Features:

• Direct-replacement ABS wheel speed sensor from Airtex Automotive Division, part number 5S7989

A faulty wheel speed sensor can trigger the ABS warning light and disable ABS and traction control. Replacing it with a quality sensor helps restore normal braking system function.
