Wheel Speed Sensor: Testing and Inspection

Wheel Speed Sensor Output Voltage Inspection
1. Turn ignition switch OFF.
2. Hoist vehicle a little.
3. Disconnect connector (1) of wheel speed sensor.
4. Connect voltmeter between connector terminals.





5. While turning wheel at a speed of approximately 2/3 to 1 full rotation per second, check AC voltage of sensor. If measured voltage is not as specified, check sensor, rotor and their installation conditions.

Reference





When using oscilloscope for this check, check if peak-to-peak voltage (1) meets specification and waveform is complete.
