Wheel Speed Sensor: Component Tests and General Diagnostics
WHEEL SPEED SENSOR OUTPUT VOLTAGE CHECK
1. Lift up the vehicle and release the parking brake.
2. Disconnect the ECU harness connector and measure from the harness side connector.
CAUTION: Set the special tool and use the check connector to inspect. Do not connect the connector (Special Tool) as marked except
when recording the waveform on a driving test. In such a case, connect the connector to the ECU.
3. Rotate the wheel to be measured at approximately 1/2 - 1 rotation per second, and check the output voltage using a circuit tester or an oscilloscope.
Output voltage:
When measuring with a circuit tester: 70 mV or more
When measuring with an oscilloscope: 200 mV p-p or more
