Vitara 4WD L4-2.0L (2003)
Wheel Speed Sensor: Testing and Inspection
Sensor Output Voltage
Output Voltage Inspection
1. Turn ignition switch to "OFF" position.
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.
Output AC voltage at 2/3 to one rotation per second (35 - 53 Hz) (Front wheel speed sensor) 100 mV or more
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 2/3 to one rotation per second (35 - 53 Hz) (Front wheel speed sensor) 150 mV or more
Removal
1. Disconnect negative cable from battery.
2. Hoist vehicle and remove wheel.
3. Disconnect front wheel speed sensor connector (1).
