Abs Wheel Speed Sensor
- Check the tip of the ABS wheel speed sensor for foreign particles or damage. If necessary, clean the tip or replace the ABS wheel speed sensor.
- Connect a 12 V power supply to No. 2 terminal of sensor connector as shown in the figure, then attach resistance to the No. 1 terminal. Rotate the wheel at about 2. 75 km/h (2 MPH), and measure the voltage using an oscilloscope.
Standard value of output voltage: 0.7 - 1.4 V
