AA80F Automatic Transmission

AA80F AUTOMATIC TRANSMISSION: AUTOMATIC TRANSMISSION SYSTEM: P0711: Transmission Fluid Temperature Sensor "A" Performance
P0711 - Transmission Fluid Temperature Sensor "A" Performance

DESCRIPTION

Refer to DTC P0712 AA80F Automatic Transmission.





MONITOR DESCRIPTION

This DTC indicates that there is a problem with output from the ATF temperature sensor and that the sensor itself is defective. The ATF temperature sensor converts the ATF temperature to an electrical resistance value. Based on the resistance, the TCM determines the ATF temperature and detects open or short circuits in the ATF temperature sensor circuit or faults in the ATF temperature sensor.

After running the vehicle for a certain period, the ATF temperature should increase. If the ATF temperature is below 20°C (68°F), or 110°C (230°F) or higher after driving the vehicle for a certain period, the TCM interprets this as a fault, illuminates the MIL and stores the DTC.

INSPECTION PROCEDURE

NOTICE:
Perform the universal trip to clear permanent DTCs AA80F Automatic Transmission System.

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.

NOTICE:
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.

1. Warm up the engine.

2. Turn the engine switch off.

3. Connect the Techstream to the DLC3.

4. Turn the engine switch on (IG).

5. Turn the Techstream on.

6. Enter the following menus: Powertrain / ECT / Data List.

7. According to the display on the Techstream, read the Data List.

TCM





HINT
- When DTC P0712 is output and the Techstream output is 150°C (302°F) or higher, there is a short circuit.
- When DTC P0713 is output 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.





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

PROCEDURE

1. CHECK DTC OUTPUT (IN ADDITION TO DTC P0711 AND P0713)

(a) Connect the Techstream to the DLC3.

(b) Turn the engine switch on (IG).

(c) Turn the Techstream on.

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

(e) Read the DTCs using the Techstream.

Result:





HINT
If any other codes besides P0711 and P0713 are output, perform troubleshooting for those DTCs first.

B -- GO TO DTC P0713 FLOWCHART AA80F Automatic Transmission

C -- GO TO DTC CHART Automatic Transmission System - AA80F
A -- Continue to next step.

2. CHECK TRANSMISSION FLUID LEVEL

(a) Check the transmission fluid level AA80F Automatic Transmission.

OK:

Automatic transmission fluid level is correct.

NG -- ADJUST FLUID LEVEL AA80F Automatic Transmission
OK -- Continue to next step.

3. CHECK HARNESS AND TRANSMISSION WIRE (TRANSMISSION WIRE - TCM, TRANSMISSION WIRE (ATF TEMPERATURE SENSOR))

(a) Disconnect the E6 TCM connector.





(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





HINT
The resistance value for the 25°C (77°F) ATF temperature condition is a reference value.

(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





NG -- CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - TCM)
OK -- Continue to next step.

4. REPLACE TCM

(a) Replace the TCM Removal.

NEXT -- PERFORM A/T CODE REGISTRATION Registration

5. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - TCM)

(a) Disconnect the E50 transmission wire connector.





(b) Disconnect the E6 TCM connector.

(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPAIR OR REPLACE TRANSMISSION WIRE Removal
