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

Description

INFOID:0000000010113671

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.
