Front Wheel Speed Sensor On-Vehicle
Inspection
S3RH0A4506005
Output Voltage Inspection
1) Disconnect negative cable from battery.
2) Hoist vehicle a little.
3) Disconnect wheel speed sensor connector.
4) Disconnect wheel speed grommet from vehicle body.
5) Connect voltmeter between connector (1) terminals.
6) While turning wheel by hand at a speed of
approximately 3/4 rotation to 1 1/4 rotation per
second, check AC voltage of sensor.
Output AC voltage at 3/4 to 1 1/4 rotation per
second
53 mV or more
7) If measured voltage is not as specified, check
sensor, ring and their installation conditions.
Reference
When using oscilloscope for this check, check if peak-to-
peak voltage (1) meets specification and waveform is
complete.
Peak-to-peak voltage at 3/4 to 1 1/4 rotation per
second
150 mV or more at 32 – 53 Hz
