1.Check whether any metallic
foreign material has adhered to the projection at the wheel
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: 1.0 - 1.5
kΩ
If the internal resistance of the wheel
speed sensor is not within the standard value, replace it
with a new wheel speed sensor.

3.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.
4.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.

Check whether the rotor teeth are
broken or deformed. Replace the driveshaft EUJ assembly for
the front side or the driveshaft EBJ assembly for the rear
side, respectively, if the teeth are damaged or
deformed.
