1. Sensor connector
2. Front wheel speed sensor
Removal and installation
1. Remove the bolt (A) fastening of the sensor of frequency of rotation of a forward wheel.
Note: Tightening torque: 6.9 - 10.8 Nm.
2. Remove the wheel arch liner.
3. Disconnect the front wheel speed sensor connector and remove the sensor.
4. Installation is carried out in the reverse order.
Checking the technical condition
1. Measure the output voltage between the wheel speed sensor terminal and «weight» body.
Attention. To protect the wheel speed sensor, a 100 ohm resistor must be included in the measuring circuit, as shown in the figure.
2. Compare the voltage changes at the output of the wheel speed sensor with the normal voltage changes at the output below.
V lower: 0.59 - 0.84 V.
V top: 1.18V - 1.68V.
Frequency range: 1 - 2,500 Hz.
