DTC P0710 A/T FLUID TEMPERATURE SENSOR CIRCUIT

Diagnostic Procedure

ECS007MA

1. 

CHECK A/T FLUID TEMPERATURE SENSOR WITH TERMINAL CORD ASSEMBLY

1.

Turn ignition switch to OFF position.

2.

Disconnect terminal cord assembly connector in engine compartment.

3.

Check resistance between terminal cord assembly connector E72 terminals 6 and 7 when A/T is cold
[20

°C (68°F)].

Is resistance approx. 2.5 k

Ω?

Yes

>> GO TO 2.

No

>> 1. Remove oil pan.

2. Check the following items:

–

A/T fluid temperature sensor
Refer to 

AT-260, "A/T FLUID TEMPERATURE SENSOR"

 .

–

Harness of terminal cord assembly for short or open

2. 

CHECK INPUT SIGNAL OF A/T FLUID TEMPERATURE SENSOR

With CONSULT-II

1.

Start engine.

2.

Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.

3.

Read out the value of “FLUID TEMP SE”.

 Without CONSULT-II

1.

Start engine.

2.

Check voltage between TCM harness connector M78 terminal 47 and ground while warming up A/T.

OK or NG

OK

>> GO TO 3.

NG

>> Check the following item:

●

Harness for short or open between TCM and terminal cord assembly (Main harness)

3. 

CHECK DTC

Perform Diagnostic Trouble Code (DTC) confirmation procedure. Refer to 

AT-255, "DIAGNOSTIC TROUBLE

CODE (DTC) CONFIRMATION PROCEDURE"

 .

OK or NG

OK

>> INSPECTION END.

NG

>> 1. Perform TCM input/output signal inspection.

2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.
