P1722 VEHICLE SPEED

Description

INFOID:0000000010113668

The vehicle speed signal is transmitted from ABS actuator and electric unit (control unit) to TCM via CAN com-

munication line.

INFOID:0000000010113669

DTC DETECTION LOGIC

DTC CONFIRMATION PROCEDURE

CAUTION:

Always drive vehicle at a safe speed.

NOTE:

Immediately after performing any “DTC CONFIRMATION PROCEDURE”, always turn ignition switch OFF.

Then wait at least 10 seconds before performing the next test.

1.

CHECK DTC DETECTION

With CONSULT

1. Turn ignition switch ON.

2. Select “Data Monitor” in “TRANSMISSION”.

3. Start engine and maintain the following conditions for at least 5 consecutive seconds.

Is “P1722” detected?

YES

>> Go to 

TM-101, "Diagnosis Procedure"

.

NO

>> Check intermittent incident. Refer to 

GI-41, "Intermittent Incident"

.

Diagnosis Procedure

INFOID:0000000010113670

1.

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

With CONSULT

Perform “Self Diagnostic Results” in “ABS”.
Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Check DTC detected item. Refer to 

BRC-82, "DTC No. Index"

 (VDC/TCS/ABS).

2.

CHECK DTC WITH TCM

With CONSULT

Perform “Self Diagnostic Results” in “TRANSMISSION”.
Is “P1722” detected?

YES

>> Replace TCM. Refer to 

TM-168, "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

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.

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

VEHICLE SPEED

: 10 km/h (6 MPH) or more
