P1705 TP SENSOR
Description
INFOID:0000000005514037
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.

Trouble diagnosis name
DTC is detected if...
Possible cause
P1722
Vehicle Speed Signal Circuit
• CAN communication with the ABS actua-
tor and the electric unit (control unit) is
malfunctioning.
• There is a big difference between the ve-
hicle speed signal from the ABS actuator
and the electric unit (control unit), and the
vehicle speed sensor signal.
• Harness or connectors
(Sensor circuit is open or shorted.)
• ABS actuator and electric unit (control
unit)
ACC PEDAL OPEN
: 1.0/8 or less

P1723 SPEED SENSOR
P1723 SPEED SENSOR
Description
INFOID:0000000005514043
The 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 primary speed sensor detects the primary pulley revolution speed and sends a signal to the TCM.

Speed Sensor Circuit
A rotation sensor error is detected because
the gear does not change in accordance
with the position of the stepping motor.
CAUTION:
One of the “P0720”, the “P0715” or the
“P0725“ is displayed with the DTC at the
same time.
• Harness or connectors
(Sensor circuit is open or shorted.)
• Secondary speed sensor
• Primary speed sensor
• Engine speed signal system
