Wheel speed sensor



PERFORMANCE ORDER

  1. Raise the vehicle and release the parking brake.
  2. Disconnect the connector from the power HECU.

Make sure that the released double-lock connector and connected to the probe connector of the wire harness side.

  1. Connect a voltmeter or oscilloscope to the pin terminals and measure the voltage generated by the sensor when the wheel rotates.

Contact socket

1 and 2: Front left sensor
19 and 20: the front right sensor

5 and 6: The rear left sensor
22 and 23: the rear right sensor

The output voltage when measuring oscilloscope: 150 mV

Withdrawal

The front wheel speed sensor

PERFORMANCE ORDER

  1. Remove the bolt of the front wheel speed sensor.
  1. Disconnect the connector and remove the front wheel speed sensor.

Rear wheel speed sensor

PERFORMANCE ORDER

  1. Remove the rear seat cushion.
  2. Remove the C-pillar trim.

  1. Between terminals of the connector, measure the resistance of the wheel speed sensor.

Resistance:

Front sensor: 1275-1495 Ohm
The back gauge: 1275-1495 Ohm

  1. Connect a voltmeter to the terminals of the sensor connector, measure the voltage generated by the sensor when the wheel rotates.

Set the voltmeter to measure AC voltage.
