Wheel Speed Sensor: Service and Repair
Rear
Rear Wheel Speed Sensor Routing at Trailing Arm
Body Routing of Speed Sensor
The wheel sensor has a permanent magnet and coil that generates a small AC voltage, due to the magnetic induction created as the tone-wheel rotates.
The rear tone-wheel (toothed sensor ring) is an integral part of the hub assembly and may be inspected by removing the wheel speed sensor and looking
through the hole, or by removing the rotor. If the tone-wheel needs to be replaced, the entire hub assembly will have to be replaced.
INSPECTION
Inspect tone-wheel for missing or cracked teeth, this can cause erratic sensor signals.
Tone-wheel should show no evidence of contact with the wheel speed sensor. If contact was made, determine cause and correct.
Excessive runout of the tone-wheel can cause erratic wheel speed sensor. Replace assembly if runout exceeds approximately 0.010 in. (0.25 mm).
