Wheel Sensors







Wheel Sensors
The wheel sensors give signals to the Electronic Control Unit (ECU) relating to wheel speed.

The voltage must be between 150 and 700 mV AC.

The gap between the sensor and sensor wheel must be 0.65 mm.

There is no Antilock Brake System (ABS) effect on the wheels at speeds below 6 km/h.
