INSPECTION
SPEED SENSOR CHECK
(1) Check the tip of the speed sensor pole piece for deposits
of metal or other foreign matter and clean the pole piece
as necessary.
Also check the pole piece for damage and replace if
damaged.
Caution
The speed sensor pole piece is magnetized by a
in magnet inside the sensor, so it tends to attract
metal. If the pole piece is damaged, accurate wheel
speed detection may not be expected.
(2) Measure resistance between speed sensor terminals.
Standard value:
Front 0.8-1.2
Rear 0.6-0.8
0.8-1.2
If the internal resistance of the speed sensor is out of
specification, replace with a new one.
(3) Check the speed sensor cable for open circuit and replace
if faulty.
NOTE
Remove the cable clamp from the body and, while flexing
the cable near the clamp, check for temporary open circuit.
Also check connector connection and terminal insertion.
ROTOR CHECK
Check the rotor for missing or worn teeth and replace if faulty.
