OPERATION
1. BEFORE TRANSMISSION FILL

This transmission requires Toyota Genuine ATF WS.

It is necessary to refill the transmission with the correct
amount of fluid.

The vehicle must remain level while adjusting the trans-
mission fluid level.

On vehicles equipped with active suspension, turn the
suspension control switch OFF if it is necessary to jack up
the vehicle with the engine running.
2. TRANSMISSION PAN FILL
(a) Remove the refill plug and overflow plug.
(b) Fill the transmission through the refill hole until fluid be-
gins to trickle out of the overflow tube.
(c) Reinstall the overflow plug.

HINT:
If you cannot add the listed amount of fluid, do the following:
(1) Install the refill plug.
(2) Allow the engine to idle with air conditioning OFF.
(3) Move the shift lever through entire gear range to cir-
culate fluid.
(4) Wait for 30 seconds with the engine idling.
(5) Stop the engine.
(6) Remove the refill plug and add fluid.
(7) Reinstall the refill plug.
4. FLUID CIRCULATION
(a) Allow the engine to idle with the air conditioning OFF.
(b) Move the shift lever through entire gear range to circulate
fluid.
5. FLUID TEMPERATURE CHECK
NOTICE:
The fluid temperature should be less than 30C (86F) be-
fore beginning the fluid temperature check.
(a) With hand-held tester
(1) Connect the hand-held tester to the DLC3.
(2) Select the tester menus: OBD/MOBD, ENGINE,
DATA LIST and A/T.
(3) Check A/T OIL TEMP.
(4) Allow the engine to idle until the fluid temperature
reaches 46C (115F).

(b) Without hand-held tester (Using A/T OIL TEMP indicator)
(1) Connect terminals between CG (4) and TC (13) of
the DLC3 using SST (09843-18040).
(2) Move the shift lever back and forth between N and
D at 1.5 seconds interval for six seconds.
(3) The D shift indicator on the combination meter
comes on for two seconds. This indicates that the
fluid temperature check mode has been started.
(4) The D shift indicator comes on again when the fluid
temperature reaches 46C (115F) and blinks
when it exceeds 56C (130F).
(5) Allow the engine to idle until the fluid temperature
reaches 46C (115F).
6. FLUID LEVEL CHECK
NOTICE:
The fluid temperature must be between 46C (115F) and
56C (130F) to check the fluid level.
(a) Remove the overflow plug with the engine idling.
(b) Check that the fluid comes out of the overflow tube.

If fluid does not come out, proceed to step 7.

If fluid comes out, wait until the overflow slows to a
trickle and proceed to step 8.
7. TRANSMISSION REFILL
(a) Install the overflow plug.
(b) Stop the engine.
(c) Remove the refill plug.
(d) Add 0.4 liters (0.42 US qts, 0.35 lmp. qts) of fluid.
(e) Allow the engine to idle and wait for 10 seconds.
(f) Proceed to step 6.
8. COMPLETE
(a) Install the overflow plug with a new gasket.
(b) Stop the engine.
(c) Install the refill plug with a new gasket.
Torque:
20 NVm (205 kgfVcm, 15 ftVlbf) for overflow plug

Circuit
DTC P0712 Transmission Fluid Temperature Sensor ºAº
Circuit Low Input
DTC P0713 Transmission Fluid Temperature Sensor ºAº
Circuit High Input
CIRCUIT DESCRIPTION
The ATF temperature sensor converts fluid temperature into a resistance value which is input into the ECM.
DTC No.DTC Detecting ConditionTrouble Area
P0710
(a) and (b) is detected momentary within 0.5 sec. when neither
P0712 or P0713 is not detected (1-trip detection logic)
(a) ATF temperature sensor resistance is less than 79 W.
(b) ATF temperature sensor resistance is more than 156 kW.
HINT:
Within 0.5 sec. the malfunction switches from (a) to (b) or from
(b) to (a)

sec. or more (1-trip detection logic)
ECM
P0713
ATF temperature sensor resistance is more than 156 kW. 15
minutes or more after the engine start DTC is detected for 0.5
sec. or more (1-trip detection logic)
MONITOR DESCRIPTION
The automatic transmission fluid (ATF) temperature sensor converts ATF temperature to an electrical resis-
tance value. Based on the resistance, the ECM determines the ATF temperature, and the ECM detects an
opens or shorts in the ATF temperature circuit. If the resistance value of the ATF temperature is less than
79 W
*1 or more than 156 kW*2, the ECM interprets this as a fault in the ATF sensor or wiring. The ECM will
turn on the MIL and store the DTC.
*1: 150C (302F) or more is indicated regardless of the actual ATF temperature.
*2: -40C (-40F) is indicated regardless of the actual ATF temperature.
HINT:
The ATF temperature can be checked on the OBD II scan tool or hand-held tester display.

INSPECTION PROCEDURE
HINT:
According to the DATA LIST displayed by the OBD ll scan tool or Hand-held tester, you can read the value
of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as a first step of
troubleshooting is one method to shorten labor time.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the OBD ll scan tool or Hand-held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Push the ºONº button of OBD ll scan tool or Hand-held tester.
(f) Select the item º/DIAGNOSIS/ENHANCED OBD ll/DATA LIST/ALL (or ATM)º.
(g) According to the display on tester, read the ºDATA LISTº.
