Circuit Description

A coil built into the input shaft speed sensor generates a pulse signal of 0-5 volts at both ends of this coil when the input shaft rotates. The pulse signal frequency increases with the increase in input shaft speed. Both ends of the coil are connected to the PCM. A coil built into the output shaft speed sensor generates a pulse signal of 0-5 volts at both ends of this coil when the output shaft rotates. The pulse signal frequency increases with the increase in output shaft speed. Both ends of the coil are connected to the PCM.
