Removal
1. Remove the seat cushion and back.
2. Disconnect the sensor connector.
3. Remove the sensor.
a) Loosen the wiring harness mounting bolts.
- Tightening torque during installation - 6 Nm
b) Unscrew the sensor mounting bolt.
Tightening torque during installation:
- 2WD models - 8 Nm
- 4WD models - 20 Nm
Examination
1. Check the rear wheel speed sensor.
a) Remove the seat cushion and back.
b) Disconnect the speed sensor connector.
c) Measure the resistance between the terminals.
- Nominal resistance - 0.8-1.4 kOhm
If the value does not correspond to the nominal value, replace the sensor.

d) Check for conductivity between each of the terminals and the sensor body. If there is conductivity, replace the sensor.
d) Connect the sensor connector.
e) Install the seat back and cushion.
2. Check that the sensor is installed correctly and that the tightening torque of the sensor mounting bolt corresponds to the permissible value.
Tightening torque:
- 2WD — 8 Nm
- 4WD — 20 Nm
3. Visually inspect the teeth of the speed sensor rotor.
a) Remove the hub assembly.
b) Check the sensor rotor teeth for scratches, cracks, deformation or missing teeth.
c) Install the hub assembly.
