How does the speedo sensor on a 96 landcruiser 80 series work?

The speedo sensor on a 1996 Land Cruiser 80 Series operates by generating electrical signals based on the rotation of the vehicle's speedometer drive gear, which is connected to the transmission. As the vehicle moves, the gear spins and the sensor detects this motion, converting it into signals that are sent to the vehicle's speedometer and engine control unit (ECU). This information is used to display the vehicle's speed and can also influence other systems such as cruise control and fuel management. If the sensor fails, it can lead to inaccurate speed readings or a non-functioning speedometer.
