Mitsubishi Galant 9G. Manual — part 1631
WHEEL SPEED SENSOR
TSB Revision
ANTI-LOCK BRAKING SYSTEM (ABS)
35B-108
NOTE: Front wheel speed rotors are integrated with
the BJ assembly of the drive shaft and cannot be dis-
assembled.
NOTE: Rear wheel speed rotors are integrated with
the rear hub assembly and cannot be disassembled.

WHEEL SPEED SENSOR REMOVAL
CAUTION
Be careful when handling the projection at the tip of the
wheel speed sensor and the toothed edge of the wheel
speed rotor so as not to damage them by contacting other
parts.
INSPECTION
M1352008400459
WHEEL 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 wheel speed sensor, causing foreign
material to easily adhere to it. The projection may not be
able to correctly sense the wheel rotation speed if foreign
matter is on it or if it is damaged.
2. Measure the resistance between the wheel speed sensor
terminals.
Standard value: 1.24
− 1.64 kΩ
3. If the internal resistance of the wheel speed sensor is not
within the standard value, replace it with a new wheel speed
sensor.

4. Remove all connections from the wheel speed sensor. The
circuit should be open between terminals (1) and (2) and the
body of the wheel speed sensor. If the circuit is not open,
replace with a new wheel speed sensor.
5. Check the wheel 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.
TOOTHED WHEEL SPEED ROTOR CHECK
Check whether the wheel speed rotor teeth are broken or
deformed. Replace the BJ assembly of the drive shaft, or the
rear hub assembly, respectively, if the teeth are damaged or
deformed.
