These replacement ABS (Anti-Lock Brake) Sensors with harnesses are 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.

Awesome auto parts company
Better than the original and great service from 1aauto
★★★★★October 18, 2018
Good sensors for the price
These appear higher quality than any of the other budget sensors Ive used in the past. Sensor output voltage was very good with the air gap properly adjusted.
However They didn't include any shims for adjustment, and the O-rings installed were a bit too large for the 1A Auto hubs I had purchased a few years back.
As long as these last for a while, I'm very pleased with this product.
