TCM output speed sensor, calculated speed

The control module receives a signal from the gearbox speed sensor which is affected by a toothed pulse wheel and calculates the vehicle speed based on the signal. The speed sensor is an "active" sensor, magnet resistive with a current modulated interface. The speed is directly proportional to the frequency.

Measurement range: 0 km/h - top speed
