P0714

Wiring Diagram:

The transaxle fluid temperature (TFT) sensor is a thermistor circuit. When the sensor is cold, it has a high resistance and high sensor voltage. As the temperature increases, this resistance and voltage decreases. The PCM supplies a five-volt signal to the sensor, which is also connected to ground. The PCM reads the voltage drop on the sensor signal lines to determine the corresponding temperature.

DTC PARAMETERS

DTC P0714 sets when the PCM/TC has detected two consecutive occurences of the 0.2 volts or 10 degree change, within one second.

IMPORTANT: The TFT sensor is continuously checked when ignition is On.

NOTICE: Visually inspect the transaxle fluid temperature wires for evidence of shorts to battery/ignition voltage. Shorts to battery/ignition voltage will skew the sensor's resistance and eventually cause DTC P0711 to set.

DIAGNOSTIC AIDS

Visually inspect the transaxle fluid temperature wires for damage. Wiggle wires while observing Scan tool and watch for a sudden shift in temperature.

Check the tightness of the female terminal grip with a spare male terminal.

When attempting to diagnose an intermittent problem use the Scan tool* to review supplemental diagnostic information. The supplemental data can be used to duplicate a problem.

* Select MALF History and DTC status from DTC menu at Scan tool.
