Todo esto es posible ya que el sensor VSS, logra observar con exactitud la velocidad de salida de la transmisión y velocidad de la rueda, calculada por la PCM.
Capacitive MEMS sensors detect changes in capacitance caused by moving elements, while piezoresistive MEMS sensors measure variations in resistance due to mechanical stress.
El sensor VSS lee la velocidad de salida de la transmisión y la velocidad de la rueda. De esta forma, es que la PCM logra calcular la velocidad del vehículo.
El sensor VSS se revisa para conocer si está desaliñado. Se puede hacer una limpieza del dispositivo y su cableado. Sin embargo, se debe manipular lo con sumo cuidado. Sigue estos pasos para extirpar sensor VSS:
Although rail vehicles occasionally do use drives without sensors, most need a rotary speed sensor for their regulator system.
Este tipo de sensor se encuentra en la carcasa del engranaje diferencial y controla la velocidad de salida del transeje. En promedio, estos sensores tienen 12 voltios de potencia de sensor.
Cuando el cuerpo del acelerador se ensucia, funciona mal, obstruye el flujo de aerofagia cerca de el motor, lo que genera problemas de rendimiento y en el paso de combustible no cabreado a través del sistema de escape.
Por lo tanto, aún queda camino por recorrer antiguamente de que estos sensores ópticos se utilicen en los sensores de velocidad contemporáneos y en los sistemas antibloqueo de frenos de los vehículos comerciales actuales.
This type of sensor normally consists of two hall effect sensors, a rare-earth magnet and appropriate evaluation electronics.
Another method used is to detect a 50 MHz output signal from the sensor when the power supply is periodically modulated at 50 MHz. It is also common for two-channel sensors to have electrically isolated channels.

Attempts are made to compensate for this by using special regulators that gradually increase the current through the LED, but unfortunately this further accelerates the aging process.
The conventional way of doing this is to measure the temperature at the sensor and use this information to compensate vehicle speed sensor the offset, but this fails for two reasons: firstly because the drift does not vary linearly with the temperature, and secondly because not even the sign of the drift is the same for all sensors.
