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.

INFOID:0000000005514042

1.

CHECK DTC WITH ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)

With CONSULT-III

Perform “Self Diagnostic Results” in “ABS”.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Check DTC detected item. Refer to 

BRC-96, "DTC No. Index"

 (VDC/TCS/ABS).

2.

CHECK DTC WITH TCM

With CONSULT-III

Perform “Self Diagnostic Results” in “TRANSMISSION”.

Is “P1722” detected?

YES

>> Replace TCM. Refer to 

TM-160, "Exploded View"

.

NO

>> GO TO 3.

3.

DETECT MALFUNCTIONING ITEMS

Check TCM connector pin terminals for damage or loose connection with harness connector.
Is the inspection result normal?

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)

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.
