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
