Component Testing

WARNING: This page is about a different car, the 2010 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the appropriate wheel speed sensor.
  2. Test for 850-1350 Ω between the signal terminal A and the low reference terminal B. During the test, check for an intermittent circuit condition by gentle moving the wheel speed sensor pigtail harness.
    • If not within the specified range, replace the wheel speed sensor.
  3. Test for infinite resistance between each terminal and the steering knuckle. Reverse the test leads, test for infinite resistance between each terminal and the steering knuckle again.
    • If less than the specified value, replace the appropriate wheel speed sensor.
  4. Spin the wheel while monitoring the voltage between the signal terminal A and the low reference terminal B. The voltage should be greater than 100 mV AC.
    • If less than the specified range, replace the wheel speed sensor.
