WARNING: This page is about a different car, the 2008 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect the wheel speed sensor connector.
- With the ignition OFF, measure for 850-1350 ohms across the wheel speed sensor.
- If the resistance is not between 850-1350 ohms replace the faulty wheel speed sensor.
- Spin the wheel. Measure across the wheel speed sensor for 100 mv AC or greater.
- If the AC voltage is less than 100 mv replace the wheel speed sensor.
