DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC P0711Transmission Fluid Temperature (TFT) Sensor Circuit Performance

Conditions for Setting the DTC
    • Transmission fluid temperature is less than 15°C (59°F)
    • Vehicle speed is 40 km/h (25 mph) or greater.
    • Conditions above continues for 10 minutes or more.

Action Taken When the DTC Sets
    • The TCM will request the illumination of malfunction indicator lamp (MIL) and store the DTC when the TCM detects a failure on the first ignition cycle.
    • No timing solenoid control N-D

Conditions for Clearing the DTC
    • The TCM turns OFF the MIL when no further failures are detected on the next 3 consecutive ignition cycles.
    • The scan tool can clear the DTC from the TCM history.
    • The TCM clears the DTC from the TCM history memory after 40 consecutive ignition cycles without fault.
    • The TCM detects the temperature of the transmission fluid is between 0-150°C (32-302°F) for 10 seconds continuously.

Cause of Failure
    • The wiring harness or the connector between the TFT sensor and the TCM
    • The TFT sensor
    • The TCM

  1. Turn OFF the ignition.
  2. Measure the resistance between the vehicle harness and transmission fluid temperature (TFT) sensor. Refer to Transmission Fluid Temperature Sensor Inspection .
  3. Disconnect the transmission control module (TCM) connector and measure the resistance between terminal A11 and A12.

Is the measurement within the specified values?

10°C (50°F)

5.80-7.09 KΩ

110°C (230°F)

0.231-0.263 KΩ

Go to Step 8

Go to Step 5

7
  1. Inspect for damage between the vehicle harness and the TFT sensor.
  2. Disconnect the transaxle harness connector of the T/M wire and inspect the resistance between the TFT sensor connector terminal 1 and 6.

Is the measurement within the specified values?

10°C (50°F)

5.80-7.09 KΩ

110°C (230°F)

0.231-0.263 KΩ

Go to Step 9

Go to Step 10

Go to Step 2

System OK

9
  1. Inspect for damage of the vehicle wiring harness or between the connectors.
  2. Test the continuity and short circuit for the vehicle wiring harness and inspect the connection condition between the transaxle harness connectors. Refer to Wiring Harness and Connector Inspection Diagnosis .

Is the condition OK?
