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.
