Wheel Speed Sensor Check
- 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.
- Measure the resistance between the wheel speed sensor terminals.
Standard value: 1.24 - 1.64 kΞ©Β
- If the internal resistance of the wheel speed sensor is not within the standard value, replace it with a new wheel speed sensor.
- 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.
- 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.
