Wheel Speed Sensor: Testing and Inspection
TONE WHEEL INSPECTION
Tone wheels can cause erratic wheel speed sensor signals. Inspect tone wheels for the following possible causes.
-
missing, chipped, or broken teeth
-
contact with the wheel speed sensor
-
wheel speed sensor to tone wheel alignment
-
wheel speed sensor to tone wheel clearance
-
excessive tone wheel runout
-
tone wheel loose on its mounting surface
Rear tone wheels are pressed onto their mounting surfaces and should not rotate independently from the mounting surface.
If a front tone wheel is found to need replacement, the tone wheel can be replaced as a separate component. See: Service and Repair/Tone
Wheel/Removal
If a rear tone wheel is found to need replacement, the axle shaft must be serviced. No attempt should be made to replace just the tone wheel.
Check the gap between the speed sensor head and the tone wheel to ensure it is within specifications. See: Brakes and Traction Control/Antilock Brakes /
Traction Control Systems/Specifications
Excessive wheel speed sensor runout can cause erratic wheel speed sensor signals. For the maximum allowed tone wheel runout specification, See:
Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Specifications. If front tone wheel runout is excessive, determine if it is caused
by a defect in the tone wheel or hub and bearing. If rear tone wheel runout is excessive, determine if it is caused by a defect in the axle shaft assembly or
hub and bearing. Replace as necessary.
