Kia Rio: Front Wheel Speed Sensor Inspection

Measure the output voltage between the terminal of the wheel speed sensor and the body ground.

•	In order to protect the wheel speed sensor, when measuring output voltage, a 120 Ω resister must be used as shown.

Compare the change of the output voltage of the wheel speed sensor to the normal change of the output voltage as shown below.

V_low: 0.7 V ~ 1.0 V

V_high: 1.4 V ~ 2.0 V

Frequency range: 1 ~ 2,500Hz
