The wheel speed sensors can detect the direction of rotation of the reluctor ring and zero speed. The sensor is more stable in high-vibration conditions and operates more efficiently than the reluctance sensor. The magneto resistive sensorвЂ™s main advantage is the ability to sense direction and operate with a wide air gap. These magnetic rings are often located on the seal of the bearing. Magneto Resistive (Active Wheel Speed Sensors)ДЄ magneto resistive sensor has a sensing element that contains an output module that is mounted on a substrate and magnetic material.

The change in amplitude can affect the switching toggle to the computer, where a cracked reluctor ring may produce an extra switching toggle.

The voltage signal will increase in amplitude with an increase in the speed of the reluctor ring. As the gap between the notch and the ring changes with the rotation of the reluctor, the sensor generates an analog sine wave voltage signal. The rotation of the reluctor ring increases and decreases the magnetic field between the notch and the tooth to generate a voltage in the coil. These sensors are less accurate and might read 3-5 mph on a scan tool when the vehicle is sitting still.

The sensor is mounted at a specific gap from a notch and tooth reluctor ring. These are typically found on pre-2003 vehicles. The variable-reluctance magnetic sensor has a permanent magnet pickup core and coil surrounding the magnet. Variable Reluctance (Passive Wheel Speed Sensors) Most vehicles in use today use two types of wheel speed sensors variable reluctance (passive) and magneto resistive (active). The average wheel bearing job may require a scan tool, scope or meter to verify the operation of the sensor. At this location, the wheel speed sensors are more accurate and often more protected from the elements. In the past decade, wheel speed sensors have been moving from differentials, axles and knuckles to inside or on the wheel bearing or hub unit. If you are replacing a wheel bearing on a late-model vehicle, you will be dealing with a wheel speed sensor.
