WHEEL SPEED SENSOR
REMOVAL AND INSTALLATION
Caution
If the vehicle is equipped with the Brembo disc brake, during maintenance, take care not to contact
the parts or tools to the caliper because the paint of caliper will be scratched. And if there is
brake fluid on the caliper, wipe out quickly.

INSTALLATION SERVICE POINT
"AAWHEEL SPEED SENSOR
INSTALLATION
Install the wheel speed sensor crossing with the parking brake
cable.
INSPECTION
CHECK OF RESISTANCE BETWEEN WHEEL SPEED
SENSOR TERMINALS
Caution
The pole piece can become magnetized because of the
magnet built into the wheel speed sensor, with the result
that metallic foreign material easily adheres to it.
Moreover, the pole piece may not be able to function to
correctly sense the wheel rotation speed if it is damaged.
1. Measure the resistance between the wheel speed sensor
terminals.
Standard value: 1.24 - 1.64 kΩ
If the internal resistance of the wheel speed sensor is
not within the standard value, replace with a new wheel
speed sensor.
2. 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 bend and pull the cable
near the clamp to check whether or not temporary
disconnection occurs. Also check the connection of the
connector and that the terminals are inserted correctly.
ABS ROTOR CHECK
Check whether ABS rotor teeth are broken or deformed, and,
if so, replace the ABS rotor.
WHEEL SPEED SENSOR INSULATION INSPECTION
1. Remove all connections from the wheel speed sensor,
and then measure the resistance between terminal 1 and
the body of the wheel speed sensor, and terminal 2 and
the body of the wheel speed sensor.
Standard value: 100 kΩor more
2. If the speed sensor insulation resistance is outside the
standard value range, replace with a new speed sensor.
