Examination
Fig. 6.67. Measuring the resistance between the sensor terminals
Measure the resistance between the sensor terminals (Fig. 6.67).
Nominal resistance:
- front wheel speed sensor – 1100 Ohm ±50%.
- rear wheel speed sensor – 1100 Ohm ±50%.
Fig. 6.68. Measuring the resistance between the sensor terminals when the wheel is rotating
While rotating the wheel, measure the voltage between the sensor terminals (Fig. 6.68).
Note: Set the voltmeter switch to measure AC voltage (AC voltage).
Nominal value: AC voltage is recorded.
