Circuit/System Description
The transmission fluid temperature (TFT) sensor is a variable resistor that measures the temperature of the transmission fluid. The engine control
module (ECM) supplies 5 volts to the TFT signal circuit and supplies a ground to the low reference circuit.
The following table illustrates the difference between temperature, resistance, and voltage:
Conditions for Running the DTC
P0712
* The engine speed is above 1,000 RPM for 7 seconds.
* This DTC runs continuously when the above condition is met.
P0713
* The engine speed is above 1,000 RPM for 7 seconds.
* This DTC runs continuously when the above condition is met.
Conditions for Setting the DTC
P0712
The TFT is greater than 145掳C (299掳F) for more than 5 seconds.
P0713
The TFT is less than -35掳C (-31掳F) for more than 5 seconds.
Action Taken When the DTC Sets
DTC P0712 and P0713 are Type C DTCs.
Conditions for Clearing the MIL/DTC
DTC P0712 and P0713 are Type C DTCs.
