Sidekick JSS 4D Hard Top 2WD L4-1.8L (1997)
Wheel Speed Sensor: Testing and Inspection
Component Inspection
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 2/3 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.
