Rear Wheel Speed Sensor

Repair Procedures

Removal

[Without ECS]

1. 1

   Remove the wheel nuts, wheel and tire (A) from the hub.

   Tightening torque: 107.9–128 N·m

   

2. 2

   Loosen the rear wheel speed sensor bolt and remove the rear wheel speed sensor.

   Tightening torque: 6.9–10.8 N·m

   

3. 3

   Loosen the rear wheel speed sensor bracket bolt.

   Tightening torque: 6.9–10.8 N·m

   

4. 4

   Disconnect the rear wheel speed sensor connector.

   

5. 5

   Install in the reverse order of removal.

Inspection

1. 1

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

   

2. 2

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

   

   V_low: 0.59–0.84 V V_high: 1.18–1.68 V Frequency range: 1–2,500 Hz
