P0725 ENGINE SPEED

P0725 ENGINE SPEED

Description

INFOID:0000000009719450

The engine speed signal is transmitted from ECM to TCM via CAN communication line.

DTC Logic

INFOID:0000000009719451

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 10 consecutive seconds.

Is “P0725” detected?

YES

>> Go to 

TM-64, "Diagnosis Procedure"

.

NO

>> Check intermittent incident. Refer to 

GI-44, "Intermittent Incident"

.

Diagnosis Procedure

INFOID:0000000009719452

1.

CHECK DTC WITH ECM

With CONSULT

1.

Turn ignition switch ON.

2.

Perform “Self Diagnostic Results” in “ENGINE”.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Check DTC detected item. Refer to 

EC-507, "DTC Index"

.

2.

CHECK DTC WITH TCM

With CONSULT

Perform “Self Diagnostic Results” in “TRANSMISSION”.

Is “P0725” detected?

YES

>> Replace TCM. Refer to

TM-165, "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?

YES

>> Replace TCM. Refer to 

TM-165, "Exploded View"

.

NO

>> Repair or replace damaged parts.

DTC

Trouble diagnosis name

DTC is detected if...

Possible cause

P0725

Engine Speed Input Circuit

• TCM does not receive the CAN communi-

cation signal from the ECM.

• Engine speed is too low while driving.

Harness or connectors
(The ECM to the TCM circuit is open or 
shorted.)

P0740 TORQUE CONVERTER

Description

INFOID:0000000009719453

• The torque converter clutch solenoid valve is activated by the TCM in response to signals sent from the vehi-

cle speed and accelerator pedal position sensors. Lock-up piston operation will then be controlled.

• Lock-up operation, however, is prohibited when CVT fluid temperature is too low.
• When the accelerator pedal is depressed (less than 2.0/8) in lock-up condition, the engine speed should not

change abruptly. If there is a big jump in engine speed, there is no lock-up.
