Examination
1. Measure the resistance between the connector pins of each sensor.
- Rated resistance - 1.25 - 1.55 kOhm
If the value is out of specification, replace the sensor.
pressure modulator.
1 - brake pipes,
2 - pressure modulator,
3 - bracket,
4 - bushing,
5 - fastening bolt.
2. Check for continuity between each of the leads and the sensor housing. If there is continuity, replace the sensor.
3. Check the correct installation of the wheel speed sensor and the compliance of the tightening torque of the sensor mounting bolt with the permissible value.
- Tightening torque - 19 Nm
4. Check the sensor rotor for scratches, cracks, deformation, or missing teeth.
5. Measure the gap between the rotor and speed sensor.
- Nominal clearance - 1.0 mm
Removal and installation
Note:
- Removal is carried out in accordance with the figure "Front wheel speed sensor".
- Install in the reverse order of removal.
- The tightening torques are shown in the figure.
