Wheel Speed Sensor: Service and Repair

WHEEL SPEED SENSOR

REMOVAL AND INSTALLATION

CAUTION:
The vehicle speed detection encoder collects any metallic particle easily, because it is magnetized. Make sure that the encoder should not collect any metallic particle. Check that there is not any trouble prior to reassembling it.

Removal Steps 1-9:





INSTALLATION SERVICE POINTS

[A] FRONT WHEEL SPEED SENSOR GROMMET/REAR WHEEL SPEED SENSOR GROMMET INSTALLATION





Install the front wheel speed sensor grommet and the rear wheel speed sensor grommet to the body panel snugly as shown in the figure.

[B] SENSOR HARNESS CLIP INSTALLATION





As shown in the figure, align the edge of front wheel speed sensor marking with the edge of sensor wiring harness clip, then perform the installation.

[C] FRONT WHEEL SPEED SENSOR CONNECTOR INSTALLATION





As shown in the figure, align the edge of front wheel speed sensor marking with the edge of clip, then perform the installation.

INSPECTION

WHEEL SPEED SENSOR CURRENT CHECK

CAUTION:





Do not connect the battery terminals in reverse as the wheel speed sensor may be damaged.

1. Connect the circuit tester to the wheel speed sensor using the special tool extra fine probe (MB992006), and measure the sensor current as a single unit.

NOTE:
When measuring at the front wheel speed sensor
^ Do not remove the front wheel speed sensor from the knuckle.

When measuring at the rear wheel speed sensor
^ Do not remove the rear wheel speed sensor from the knuckle.

Standard value: 5.9 to 8.4 mA or 11.8 to 16.8 mA
2. If the measurement value is not within the standard value range, replace the wheel speed sensor with a new one.

WHEEL SPEED SENSOR INSULATION CHECK





1. Connect the circuit tester to the wheel speed sensor using the special tool extra fine probe (MB992006), and measure the insulation resistance between terminal No. 1/2 and the wheel speed sensor body as a single unit.
Standard value: 5 MOhms or more
2. If the insulation resistance is not within the standard value range, replace the wheel speed sensor with a new one.
