FRONT SPEED SENSOR/REAR SPEED SENSOR
INSTALLATION
The clearance between the wheel speed sensor and the ABS
rotor’s toothed surface is not adjustable, but measure the
distance between the sensor installation surface and the ABS
rotor’s toothed surface.
Standard value: 28.2 - 28.5 mm

SPEED SENSOR
1. Check whether any metallic foreign material has adhered
to the pole piece at the speed sensor tip, and if so, remove
it.
Also check whether the pole piece is damaged, and if
so, replace it with a new one.
NOTE
The pole piece can become magnetized because of the
magnet but into the speed sensor, with the result that
metallic foreign material easily adheres to it. Moreover,
the pole piece may not be able to function to correctly
sense the wheel rotation speed if it is damaged.
2. Measure the resistance between the speed sensor
terminals.
Standard value: 1.0 - 1.5 k
W
If the internal resistance of the speed sensor is not within
the standard value, replace with a new speed sensor.
3. Check the speed sensor cable for breakage, damage
or disconnection; replace with a new on e if a problem
is found.
NOTE
When checking for cable damage, remove the cable clamp
part from the body and then bend and pull the cable
near the clamp to check whether or not temporary
disconnection occurs.
