OUTPUT VOLTAGE INSPECTION
1. Turn ignition switch "OFF".
2. Hoist vehicle a little.
3. Disconnect connector 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.

Output AC voltage at 213 to one rotation per second (35 - 53 Hz): 106 mV or more

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 meets specification and waveform is complete.

Peak-to-peak voltage at 2/3 to one rotation per second (35 - 53 Hz): 150 mV or more
