Sensor, speed / RPM - 821 676 TOPRAN

The TOPRAN brand Sensor, speed is one of the many automotive sensors responsible for generating signals of measurement information, transmitting it, further transforming and processing the electronic control unit and some other devices. If the car does not have an ECU, the need for sensors does not decrease. The release of even the least important of the sensors affects at least how comfortable it will be to operate the car. Since the speed sensor is quite important, let's try to understand the features of its device, analyze the main malfunctions and try to understand how, if necessary, even an inexperienced motorist can replace it.

The usage of the speed sensor

A special controller has been introduced into the speed detection system, which receives a pulse signal from the sensor. Controller transmits the signal to the electronic control unit, which calculates the amount of fuel required for optimal engine operation. For example, if the speed of a car decreases, the amount of fuel supplied to the engine decreases as well. Due to this, it is possible to significantly save fuel and operate the engine in the gentlest mode.
