Repair Procedures

Removal

1. Remove the front wheel speed sensor mounting bolt (A) and cable mounting bolt (B).




2. Remove the front wheel speed sensor bracket (A).




3. Remove the front wheel guard.
4. Disconnect the front wheel speed sensor connector (A) , then remove the front wheel speed sensor.

Inspection

1. Measure the output voltage between the terminal of the wheel speed sensor and the body ground.

CAUTION:
In order to protect the wheel speed sensor, when measuring output voltage, a 100 Ohms resister must be used as shown.




2. 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 : 0.59 V ~ 0.84 V
V_high : 1.18 V ~ 1.68 V
Frequency range : 1 - 2,500 Hz
