Wheel Speed Sensor Screen
The wheel speed sensor screen allows the technician to spin the wheels and record the sensor output. Addi onally,
there is a sensor air gap field which indicates the speed when the sensor starts registering speed. A lower air gap
speed value (e.g. 3 to 4) indicates a properly adjusted wheel speed sensor. An air gap speed value higher than 5
indicates that the wheel speed sensor needs to be adjusted by installing the sensor closer to the tone ring elimina ng
the distance between the sensor and tone ring.
