ABS Speed Sensor with Harness - 1AERK00121

This part replaces:

  • DORMAN 970-010 x2
  • OE # 15997039 x2

  • New

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.


  • Comes as a PAIR
    • Fits both the LH (Driver Side) & RH (Passenger Side) FRONT WHEEL
  • Includes Harnesses with Plugs
  • Correct connectors and wire length
  • Built to strict quality control standards
  • Replaces dealer part numbers: 15997039
  • Direct replacements
  • 100% electrically factory tested
  • Plugs into existing body mounted ABS harness
    • No Splicing needed
  • Fits 4WD models as well as 2WD Blazer models with RPO code ZR2 suspension as listed per applications

Note: If your vehicle requires a match to an RPO (Regular Production Option) code, you can usually find it on your original window sticker and sometimes either on the inside of your trunk lid, spare tire cover, glove box door, or the front driver's side door shell.
