If faulty, replace with a new one.
• Keep magnets (including magnetic pick-up
tools, magnetic screwdrivers, etc.) away
from the wheel sensor rotor.
• Do not drop or shock the wheel sensor or
the wheel sensor rotor.

• Front wheel sensor "1"
Cracks/bends/distortion → Replace.
Iron powder/dust → Clean.
2. Check:
• Front wheel sensor rotor "1"
Cracks/damage/scratches → Replace the
front wheel sensor rotor.
Iron powder/dust/solvent → Clean.
TIP
• The wheel sensor rotor is installed on the inner
side of the wheel hub.
• When cleaning the wheel sensor rotor, be
careful not to damage the surface of the rotor
magnet.
3. Measure:
• Wheel sensor rotor deflection
Out of specification → Clean the installation
surface of the wheel sensor rotor and correct
the wheel sensor rotor deflection, or replace
the wheel sensor rotor.
