Description

INFOID:0000000000988713

Electric throttle control actuator consists of throttle control motor, accelerator pedal position sensor, throttle
position sensor etc. The actuator sends a signal to the ECM, and ECM sends the signal to TCM with CAN
communication.

P1723 CVT SPEED SENSOR FUNCTION

P1723 CVT SPEED SENSOR FUNCTION

Description

INFOID:0000000000988719

The vehicle speed sensor CVT [output speed sensor (secondary speed sensor)] detects the revolution of
parking gear and generates a pulse signal. The pulse signal is sent to the TCM, which converts it into vehicle
speed.
The input speed sensor (primary speed sensor) detects the primary pulley revolution speed and sends a sig-
nal to the TCM.
