Repair Procedures of Front Wheel Speed Sensor

Removal

1. 1
   Turn the ignition switch OFF and disconnect the negative (-) battery cable.
2. 2
   Remove the front wheel and tire (A) from the front hub.

   Tightening torque: 88.3 ~ 108 N·m

3. 3
   Remove the wheel speed sensor bracket bolt (A) and the wheel speed sensor mounting bolt (B).

   Tightening torque: 6.9 ~ 10.8 N·m

   

4. 4
   Install in the reverse order of removal.
5. 5
   Turn the ignition switch OFF and disconnect the negative (-) battery cable.
6. 6
   Remove the front wheel and tire (A) from the front hub.

   Tightening torque: 88.3 ~ 108 N·m

7. 7
   Remove the wheel speed sensor bracket bolt and disconnect the wheel speed sensor connector (A).

   Tightening torque: 6.9 ~ 10.8 N·m

   

8. 8
   Install in the reverse order of removal.

Inspection

1. 1
   Turn the ignition switch OFF and disconnect the negative (-) battery cable.
2. 2
   Measure the output voltage between the wheel speed sensor terminal and the body ground.

   To protect the wheel speed sensor when measuring the output voltage, use a 100 Ω resistor as shown below.

   

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

   

   V_low: 0.59 V ~ 0.84 V V_high: 1.18 V ~ 1.68 V Frequency range: 1 ~ 2000 Hz
