REMOVAL SERVICE POINT

.

<<A>> FRONT SPEED SENSOR/REAR SPEED SENSOR 
REMOVAL

CAUTION

Be careful when handling the projection at the tip of the 
speed sensor and the toothed edge of the ABS rotor so as 
not to damage them by contacting other parts.

INSPECTION

M1352008400471

.

SPEED SENSOR CHECK
1. Check whether any metallic foreign material has adhered to 

the projection at the speed sensor tip. Remove any foreign 
material. Also check whether the pole piece is damaged. 
Replace it with a new one if it is damaged.
NOTE: The projection can become magnetized due to the 
magnet inside the speed sensor, causing foreign material to 
easily adhere to it. The projection may not be able to cor-
rectly sense the wheel rotation speed if foreign matter is on 
it or if it is damaged.

2. Measure the resistance between the speed sensor 

terminals.

Standard value: 1.0 

 1.5 k

3. If the internal resistance of the speed sensor is not within the 

standard value, replace it with a new speed sensor.

4. Remove all connections from the speed sensor. The circuit 

should be open between terminals (1) and (2) and the body 
of the speed sensor. If the circuit is not open, replace with a 
new speed sensor.

5. Check the speed sensor cable for breakage, damage or 

disconnection. Replace with a new one if a problem is found.
NOTE: When checking for cable damage, remove the cable 
clamp part from the body and then gently bend and pull the 
cable near the clamp.
