Circuit Description

A coil built into the input shaft speed sensor generates a 0-5 volt pulse signal at both ends of this coil when the input shaft rotates. The pulse signal frequency increases with a increase in input shaft speed. Both ends of the coil are connected to the PCM. The PCM detects the input shaft speed by the signal input from the input shaft speed sensor. The input shaft speed sensor generates the pulse signal as the teeth of the reverse clutch retainer pass the magnetic tip of the sensor.
