Inspection Procedure

WARNING: This page is about a different car, the 2007 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

HINT:

Using the intelligent tester'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 the intelligent tester to the CAN VIM. Then connect the CAN VIM to the DLC3.
Turn the ignition switch ON and turn the tester ON.
Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST.
Follow the instructions on the tester and read the DATA LIST.

DATA LIST

Item	Measurement Item/Range (Display)	Normal Condition	Diagnostic Note
A/T OIL TEMP1	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 DISPLAYED MALFUNCTION CHART

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 B27 wire connector.

Measure the resistance of the transmission wire.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION CHART

Tester Connection	Specified Condition
1 (THO) - 6 (E2)	90 Ω to 156 kΩ
1 (THO) - Body ground	1 MΩ or higher
6 (E2) - Body ground	1 MΩ 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.

Standard resistance

ATF TEMPERATURE SPECIFIED CONDITION CHART

ATF Temperature	Specified Condition
10°C (68°F)	6.4 kΩ
110°C (230°F)	0.2 kΩ

NG: REPAIR OR REPLACE TRANSMISSION WIRE

OK: Go TO NEXT STEP.

CHECK WIRE HARNESS (TRANSMISSION WIRE - ECM)

Disconnect the B30 ECM connector.

Measure the resistance of the wire harness side connector.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION CHART

Tester Connection	Specified Condition
B30-72 (THO1) - B30-95 (ETHO)	90 Ω to 156 kΩ
B30-72 (THO1) - Body ground	1 MΩ or higher
B30-95 (ETHO) - Body ground	1 MΩ or higher

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR
