Front Wheel Speed Sensor Repair procedures


  1. Remove the tire.

Tightening torque: 107.9 - 127.5 N*m (11.0 - 13.0 kgf*m, 79.6 - 94.0 lb*ft)



Be careful not to damage the hub bolts when removing the wheel & tire.

  1. Remove the wheel speed sensor bolt (A).

Tightening torque: 6.8 - 10.7 N*m (0.7 - 1.1 kgf*m, 5.0 - 7.9 lb*ft)

  1. Remove the wheel speed sensor bracket bolt (A).

Tightening torque : 8.8 - 13.7 N*m (0.9 - 1.4 kgf*m, 6.5 - 10.1 lb*ft)

  1. Remove the front wheel guard.

    (Refer to body - "Front Wheel Guard")

  2. Disconnect the front wheel speed sensor.

  1. Installation is the reverse of removal.


  1. 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 Ω resister must be used as shown.

  1. 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
