P0712



DTC P0712 (European and N. American Emissions)

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC P0712 Transmission Fluid Temperature (TFT) Sensor Circuit Low Voltage

Conditions for Setting the DTC

* The transmission control module (TCM) detects that the analog-to-digital (A/D) value of the transmission fluid temperature (TFT) sensor signal is less than 10 for 5 minutes continuously after one occurrence of this detection. A/D value 10: 24 Mv
* The TCM does not detect pass criteria achieved.


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.
* The 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 MIL 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 0-150°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
