DTC P0712

DTC Descriptor

This diagnostic procedure supports the following DTC:
DTC P0712
- Transmission Fluid Temperature 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 sensor signal is less than 10 for 10 s continuously after one occurrence of this detection. A/D value 10: 50 mv
* The TCM does not detect pass criteria achieved.

Action Taken When the DTC Sets

* The TCM will request the illumination of hold/malfunction indicator lamp (MIL) and store the DTC when the TCM detects failures on 2 consecutive ignition cycles.
* 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 hold/malfunction indicator lamp (MIL) when no further failures are detected for three 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 s continuously.

Diagnostic Aids

Failure caused by:

* The wiring harness or the connector between the transmission fluid temperature sensor and the TCM
* The transmission fluid temperature sensor
* TCM
