Check Of Resistance Between Wheel Speed Sensor Terminals

WARNING: This page is about a different variant/trim than selected.

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 correctly sense the wheel rotation speed if foreign matter is on it or if it is damaged.
Measure the resistance between the speed sensor terminals.
- Standard value: 1.24 - 1.64 kohm
If the internal resistance of the speed sensor is not within the standard value, replace it with a new speed sensor.

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.
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.
