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.
