Rear Wheel Speed Sensor: Inspection

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

NOTE:

In order to protect the wheel speed sensor, when measuring output voltage, a 100 Ω resistor must be used as shown below:

- I low: 5.88 - 8.4 mA
- I middle: 11.76 - 16.8 mA (SPAS)
- I high: 11.76 - 16.8 mA (N-SPAS), 23.52 - 33.6 mA (SPAS)
- Frequency range: 0 - 2, 500 Hz
