SPEED SENSOR

(1) Check whether ay metallic foreign material has adhered
t0the pole pieceat the speedsensor tip,and,is SO
remove

Alsocheckwhether the pole piece is daraged,and,
SO, replace it witha new one

NOTE

The pole piece can become magnetizedbecause of the
magnet built into the speed sensor,with the result that
metallic foreign material easily adheres to it.Moreover ,
the pole piece maynot be able to function to correctly
sense the wheel rotation speed if it iS damaged.

(2)Measure the resistancebetween the speedsensor ter-
minals

Standard value:
Front:0.9-1.1 kS2
Rear:1.3-2.1 kS2
theinternalresistanceofthe speedsensorisnot
within the standardvalue, replace it withnew speed
sensor.

(3) Remove all connections from the speed sensor; and then
measure the resistance between terminals (1) and (21 and
the body of the speed sensor

Standard value: 100kS2 or more

Ifthe speed sensor insulation resistance is outside the stan-
dard value range , replace with a new speed sensor:

(4) Check the speed sensor cable for breakage, damageor
disconnection; replacewithnewoneifproblem is
found.
