P1705 THROTTLE POSITION SENSOR

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.

A rotation sensor error is de-
tected because the gear does
not change in accordance with
the position of the stepping mo-
tor.

CAUTION:

SEN/CIR AT”, the “P0715 IN-
PUT SPD SEN/CIRC” or the
“P0725 ENGINE SPEED SIG“
is displayed with the DTC at
the same time.

• Harness or connectors

(Sensor circuit is open or
shorted.)

• Output speed sensor (Sec-

ondary speed sensor)

• Input speed sensor (Primary

speed sensor)

• Engine speed signal system
