Inspection Procedure

WARNING: This page is about a different car, the 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

HINT:

Using Techstream's Data List allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the Data List early in troubleshooting is one way to save time.

NOTE: In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

Warm up the engine.
Turn the ignition switch OFF.
Connect Techstream to the DLC3.
Turn the ignition switch ON and turn the tester ON.
Enter the following menus: Powertrain / Engine and ECT / Data List.
Follow the instructions on the tester and read the Data List.

ECM:

ECM DATA LIST REFERENCE

Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
A/T Oil Temperature 1	ATF temperature sensor value/ Min.: -40°C (-40°F) Max.: 215°C (419°F)	After stall test: Approximately 80°C (176°F) Equal to ambient temperature while engine is cold	If value is -40°C (-40°F) or "150°C (302°F) or more", ATF temperature sensor circuit is open or short circuited

HINT:

When DTC P0712 is output and the tester output is 150°C (302°F) or more, there is a short circuit.
When DTC P0713 is output and the tester output is -40°C (-40°F), there is an open circuit. Measure the resistance between terminal THO1 (THO) and the body ground.

TEMPERATURE SPECIFICATION

Temperature Displayed	Malfunction
-40°C (-40°F)	Open circuit
150°C (302°F) or more	Short circuit

HINT:

If a circuit related to the ATF temperature sensor becomes open, P0713 is set in approximately 0.5 seconds.
It is not necessary to inspect the circuit when P0711 is set.

INSPECT TRANSMISSION WIRE (ATF TEMPERATURE SENSOR)

Disconnect the B32 wire connector.

Measure the resistance of the transmission wire.

Standard resistance

RESISTANCE SPECIFICATION

Tester Connection	Specified Condition
1 (THO) - 7 (E)	79 Ω to 156 kΩ
1 (THO) - Body ground	10 kΩ or higher
7 (E) - Body ground	10 kΩ or higher

HINT:

If the resistance is out of the specified range of either of the ATF temperatures shown in the table below, the driveability of the vehicle may decrease.

ATF TEMPERATURE AND RESISTANCE SPECIFICATION

ATF Temperature	Specified Condition
10°C (50°F)	5 to 8 kΩ
25°C (77°F)	2.5 to 4.5 kΩ
110°C (230°F)	0.22 to 0.28 kΩ

NG: REPAIR OR REPLACE TRANSMISSION WIRE

OK: Go to Next Step

CHECK WIRE HARNESS (TRANSMISSION WIRE - ECM)

Disconnect the B30 ECM connector.

Fig 2: Identifying B30 ECM Connector Terminals

Measure the resistance of the wire harness side connector.

Standard resistance

RESISTANCE SPECIFICATION

Tester Connection	Specified Condition
B30-126 (THO1) - B30-124 (ETHO)	79 Ω to 156 kΩ
B30-126 (THO1) - Body ground	10 kΩ or higher
B30-124 (ETHO) - Body ground	10 kΩ or higher

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR

OK: REPLACE ECM
