Rear Wheel Speed Sensor on-Vehicle Inspection
Rear Wheel Speed Sensor On-Vehicle InspectionOutput Voltage Inspection
1) Turn ignition switch OFF.
2) Remove quarter inner trim (1).
3) Turn over floor carpet.
4) Hoist vehicle.
5) Disconnect connector of wheel speed sensor.
6) Connect voltmeter between connector (1) terminals.
7) While turning wheel at a speed of approximately 3/4 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
8) 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
