## 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
