Removal

Remove the front wheel and tire.

Tightening torque:

88.3 ~ 107.9 N.m (9.0 ~ 11.0 kgf.m, 65.1 ~ 79.6 lb-ft)

Remove the front wheel speed sensor mounting bolt (A).

Tightening torque:

6.9 ~ 10.8 N.m (0.7 ~ 1.1 kgf.m, 5.1 ~ 8.0 lb-ft)

3.	Remove the front wheel guard .

4.	Remove the front wheel speed sensor cable mounting bolt.

5.	Disconnect the front wheel speed sensor connector, then remove the front wheel speed sensor.

6.	Installation is the reverse of removal.

Inspection

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

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

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 ~ 2,500Hz
