ON-VEHICLE SERVICE
WHEEL SPEED SENSOR OUTPUT VOLTAGE
CHECK
1. Lift up the vehicle and release the parking brake.
2. Pull the pusher in the direction indicated by the arrow
and disconnect the connector.
3. Use the special tool (inspection harness for connector
pin contact pressure) to measure the output voltage at
the harness-side connector.
4. 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:
50 mV or more
When measuring with an oscilloscope:
120 mV p-p or more
5. If the output voltage is lower than the above values, the
reason could be as follow:
Faulty wheel speed sensor.
So replace the wheel speed sensor.
