DTC P0713 Non European Emissions

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC P0713 Transmission Fluid Temperature (TFT) Sensor Circuit High Voltage

Conditions for Setting the DTC

    • Transmission control module (TCM) detects that analog-to-digital (A/D) value of transmission fluid temperature (TFT) sensor signal is less than 15 and the minimum A/D value is more than 943, when it is past 15 minutes after ignition ON--A/D value 943:4.7 V
    • After 1 occurrence of above detection
    • Gear selector position is except P and N
    • Engine revolution is 400 RPM or greater

Action Taken When the DTC Sets

    • TCM will request the illumination of the hold lamp and store the DTC when the TCM detects a failures on the first ignition cycle.
    • TCM judges the temperature of the transmission fluid is 200°C (392°F)
    • No lockup control
    • No 4th gear
    • No self-learning control
    • No timing solenoid control N-D

Conditions for Clearing the DTC

    • The TCM turns off the hold lamp when no further failures are detected on the next 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°C and 150°C for 10 seconds continuously.

Cause of Failure

    • Wiring harness or connector between TFT sensor and TCM
    • TFT sensor
    • TCM
