6. Install:
• Front wheel sensor
• Front wheel sensor bracket
Front wheel sensor bolt
7 N·m (0.7 kgf·m, 5.1 lb·ft)
ECA21020
NOTICE
Make sure there are no foreign materials in
the front wheel sensor rotor and front wheel
sensor. Foreign materials cause damage to
the front wheel sensor rotor and front wheel
sensor.
TIP
When installing the front wheel sensor, check
the front wheel sensor lead for twists.
7. Measure:
• Distance "a"
(between the wheel sensor rotor "1" and front
wheel sensor "2")
Out of specification  Check the wheel bear-
ing for looseness, and the front wheel sensor
and sensor rotor installation conditions
(warpage caused by overtorque, wrong in-
stallation direction, rotor decentering, LOC-
TITE® on the mounting surface of the rotor,
deformation caused by an impact during ser-
vice and caught foreign materials). If there is
any defective part, repair or replace the de-
fective part.
Distance "a" (between the front
wheel sensor rotor and front
wheel sensor)
1.0–1.8 mm (0.04–0.07 in)
TIP
Measure the distance between the front wheel
sensor rotor and front wheel sensor in several
places in one rotation of the front wheel. Do not
turn the front wheel while the thickness gauge is
installed. This may damage the front wheel sen-
sor rotor and the front wheel sensor.
