INSPECTION PROCEDURE

Note. Perform the universal trip to clear permanent DTCs. Refer to DTC CHECK / CLEAR [01/2012 - ] .

1. DATA LIST HINT: Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic 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 engine switch off. Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Data List. According to the display on the Techstream, read the Data List.

HINT: When DTC P0712 is stored and the Techstream output is 150°C (302°F) or higher, there is a short circuit. When DTC P0713 is stored and the Techstream output is -40°C (-40°F), there is an open circuit. Check the temperature displayed on the Techstream in order to check if a malfunction exists. Temperature Displayed Malfunction -40°C (-40°F) Open circuit 150°C (302°F) or higher Short circuit If a circuit related to the ATF temperature sensor becomes open, P0713 is immediately stored (in 0.5 seconds). When P0713 is stored, P0711 cannot be stored. It is not necessary to inspect the circuit when P0711 is stored.

[Vehicle Condition] The throttle valve opening angle is less than 35%. The vehicle speed is 60 km/h (38 mph) or more. HINT: This test can be conducted when the vehicle speed is 60 km/h (38 mph) or more. Perform this test while driving in 5th or 6th gear. Lightly depress the accelerator pedal and check that the engine speed does not change abruptly. HINT: When changing the accelerator pedal opening angle while driving, if the engine speed does not change abruptly, lock-up is on. Slowly release the accelerator pedal in order to decelerate, but do not fully release the pedal (fully releasing the pedal will close the throttle valve and lock-up may be turned off automatically).
