Inspection
1.
Turn ignition switch OFF and disconnect the negative (-) battery cable.
2.
Measure the output voltage between the terminal of the wheel speed sensor and the body ground.
   
To protect the wheel speed sensor when measuring the output voltage, a 100 ? resister must be used as shown below.

3.
Compare the change of the output voltage of the wheel speed sensor to the normal change of the output voltage as shown below.


V_low: 0.59V ~ 0.84V
V_high: 1.18V ~ 1.68V
Frequency range: 1 ~ 2,000Hz
