Rear wheel speed sensor.
1 - sensor wire, 2 - wheel speed sensor.
Withdrawal
1. Remove the rear seats (see chapter "Body").
2. Remove the rear pillar assembly (see chapter "Body").
3. Jack up the car, turn away bolts and remove a back wheel.
- Tightening torque: 90-110 Nm
4. Disconnect the rear wheel speed sensor connector and remove the sensor.
Examination
1. Connect an ohmmeter between the wheel speed sensor leads and measure the resistance. If the resistance is out of specification, replace the sensor.
- Rated resistance: 1275±1495 ohm
2. Connect a voltmeter between the wheel speed sensor leads and measure the voltage while the wheel is rotating. In good condition, AC voltage should be recorded.
Note: set the voltmeter switch to measure AC voltage (AC voltage).
3. Check the voltage at the wiring harness connector terminals.
- A) Raise the vehicle on the lift and release the parking brake lever.
- b) Disconnect the connector from the ABS/EBD/TCS electronic control unit.
- V) Rotating the wheel by hand at a frequency of 0.5-1 revolution per second, measure the voltage at the wire harness connector terminals.
- Rated voltage: 100mV or more
Wheel speed sensor | connector pins |
rear left | 6 ↔ 5 |
rear right | 23 ↔ 22 |
Installation
The speed sensor is installed in the reverse order of removal, the bolt torque is indicated in the text of the removal procedure.
