Faulty Wheel Speed Sensor Input

Trouble code will be set if ECU detects wheel speed sensor has no input signal. Trouble code will also be set if wheel speed sensor voltage output is low while vehicle is driven. Inspect wheel speed sensor wiring harness for open. If open is not found, go to next step. If open is found, replace wheel speed sensor.
Test wheel speed sensor. See WHEEL SPEED SENSOR TEST under DIAGNOSIS & TESTING. Replace the wheel sensor as necessary. Make sure the wheel speed sensor-to-rotor gap is within specification. Refer to WHEEL SPEED SENSOR ADJUSTMENT under ADJUSTMENTS.
