This replacement ABS (Anti-Lock Brake) Sensor with harness is just what you need to get your vehicle's ABS system in good operating condition again!

A bad, corroded, frayed, or malfunctioning ABS sensor can cause an ABS light to illuminate on your instrument panel, and store an ABS diagnostic error code. If your ABS sensor or wiring harness is corroded or damaged it will prevent your ABS sensor, and ABS system from working properly.
