Faulty Wheel Speed Sensor Input
- Trouble code will set if ECU detects wheel speed sensor has no input signal. Trouble code will also set if wheel sensor voltage output is low while driving vehicle.
- Inspect condition of sensor rotor. Damaged rotor teeth can set code. Inspect wheel sensor wiring harness for open or poor connection. See WIRING DIAGRAM. Repair or replace if necessary. If no open circuit or poor connection is found, go to next step.
- Test wheel speed sensor. See WHEEL SPEED SENSOR under COMPONENT TESTING. Replace wheel sensor as necessary. Ensure wheel speed sensor-to-rotor gap is within specification. See WHEEL SPEED SENSOR under ADJUSTMENTS.
