Wheel Sensor
WARNING: This page is about a different car, the 2000 Nissan Pathfinder, 2000 Infiniti QX4, and 1999 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
Measure resistance between wheel sensor terminals. Resistance should be 900-1100 ohms (front wheel sensor) and 1440-1760 ohms (rear wheel sensor). If resistance is not as specified, replace sensor.
