Front Wheel Speed Sensor: Inspection

WARNING: This page is about a different car, the 2007 Kia Optima, 2007 Kia Magentis, 2006 Kia Optima, and 2006 Kia Magentis. However, it is still accessible from the selected car via links, so may be relevant.

Measure the output voltage between the terminal of the wheel speed sensor and the body ground.
CAUTION: In order to protect the wheel speed sensor, when measuring output voltage, a 100 Ω resistor must be used as shown.
