Repair Procedures of Front Wheel Speed Sensor

Removal

1. 1
   Loosen the wheel nuts slightly. Raise the vehicle and make sure it is securely supported.
2. 2
   Remove the front wheel and tire (A) from the front hub.

   Tightening torque: 107.9 - 128 N·m

   

   Be careful not to damage the hub bolts when removing the front wheel and tire (A).

3. 3
   Loosen the mounting bolt and disconnect the wheel speed sensor cable from the strut assembly.

   Tightening torque: 8.8 ~ 13.7 N·m

   

4. 4
   Remove the wheel speed sensor cable bracket bolt (A).

   Tightening torque: 7.8 ~ 11.8 N·m

   

5. 5
   Remove the front wheel guard.
6. 6
   Disconnect the wheel speed sensor connector (A), then remove it.

   

7. 7
   Loosen the bolt and remove the wheel speed sensor (A).

   Tightening torque: 7.8 ~ 11.8 N·m

   

8. 8
   To install, reverse the removal procedure.

Inspection

1. 1
   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, a 100 Ω resistor must be used as shown in the illustration.

   

2. 2
   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 ~ 2500 Hz
