Anti-Lock Brake System Speed Sensors
Overview

NTK anti-lock brake system (ABS) sensors are designed as direct OE replacements, delivering longer component life with heavier wire insulation and weather pack connectors.

Purpose

  • The anti-lock brake system (ABS) sensors monitor the vehicle wheel speed
  • The ABS control module uses the information received from the ABS wheel speed sensors for several systems such as anti-lock brake, traction control and stability control systems.

Function

NTK anti-lock brake system (ABS) sensors are available in either analog (inductive principle) or digital (hall effect) technologies. The two technologies are not interchangeable.

  • Analogue (Inductive) Passive Sensor
    • Generates a signal, no external power supply
    • Wave-form output signal
    • Only signal when wheel turns
    • Voltage rises with wheel speed, and depends on distance to wheel (“G“)
    • 2 or 3 Pins (3rd for shield)

Digital (Hall Effect) Active Sensor

  • Integrated electronics
  • External power supply
  • Square output signal proportional to wheel speed
  • Can detect a position even if the wheel is at a standstill
  • 3 Pins

Position

At each wheel, the differential or transmission tail shaft housing

Cause for replacement

  • ABS/brake lamp illumination
  • No/erratic ABS operation
  • No/erratic traction control operation
  • No/erratic stability control operation

Anatomy and Construction

The NTK Difference

  • Glass reinforced plastic for superior resistance to contamination
  • Includes all necessary brackets and hardware
  • Application specific harness length
