P0711

U341E AUTOMATIC TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: P0711: Transmission Fluid Temperature Sensor "A" Performance
P0711 - Transmission Fluid Temperature Sensor "A" Performance

DESCRIPTION

The ATF (Automatic Transmission Fluid) temperature sensor converts the fluid temperature into a resistance value which is input into the ECM.





MONITOR DESCRIPTION

The ATF temperature sensor converts the ATF temperature to an electrical resistance value. Based on the resistance, the ECM determines the ATF temperature and detects opens or shorts in the ATF temperature circuit.

After driving the vehicle for a certain period, the ATF temperature should increase. When the ATF temperature is below 20°C (68°F), the ECM interprets this as a fault, and turns on the MIL, and stores the DTC.

When the ATF temperature is 100°C (212°F) or more and engine coolant temperature reaches 60°C (140°F) after engine cold start, the ECM also determines this as a fault, turns on the MIL, and stores the DTC.

INSPECTION PROCEDURE

NOTICE:
- Perform the universal trip to clear permanent DTCs Reading and Clearing Diagnostic Trouble Codes.
- If P0711 and P2610 are output at the same time, use Techstream to check that the ATF temperature is in the "Normal Condition". If the ATF temperature is in the "Normal Condition", refer to P2610 P2610.

HINT
Using a 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.

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

1. READ DATA LIST

(a) Warm up the engine.

(b) Turn the ignition switch off.

(c) Connect the Techstream to the DLC3.

(d) Turn the ignition switch to ON.

(e) Turn the Techstream on.

(f) Enter the following menus: Powertrain / Engine and ECT / Data List.

(g) According to the display on the Techstream, read the Data List.





HINT
When DTC P0712 is output and the Techstream output is 150°C (302°F), there is a short circuit.

When DTC P0713 is output and the Techstream output is -40°C (-40°F), there is an open circuit.

Measure the resistance between terminal THO (TH01) and body ground.





HINT
If a circuit related to the ATF temperature sensor becomes open, P0713 is immediately set (in 0.5 seconds).

When P0713 is set, P0711 cannot be detected.

It is not necessary to inspect the circuit when P0711 is set.

PROCEDURE

1. CHECK OTHER DTCS OUTPUT (IN ADDITION TO DTC P0711)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

(e) Read the DTCs using the Techstream.

Result





HINT
If any other codes besides "P0711" are output, perform troubleshooting for those DTCs first.

B -- GO TO DTC CHART Automatic Transaxle System - U341E
A -- Continue to next step.

2. CHECK TRANSMISSION FLUID LEVEL

OK:

Automatic transmission fluid level is correct.

NG -- ADD FLUID

OK -- REPLACE TRANSMISSION WIRE (ATF TEMPERATURE SENSOR) Removal
