P1705 THROTTLE POSITION SENSOR

Description

INFOID:0000000003806452

The electric throttle control actuator consists of throttle control motor, accelerator pedal position sensor, throt-
tle position sensor, etc. The actuator sends a signal to the ECM, and ECM sends the signal to TCM via CAN
communication.

P1723 CVT SPEED SENSOR FUNCTION

Description

INFOID:0000000003806458

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 the sig-
nal to the TCM.
