P0711

Wiring Diagram:

The transaxle fluid temperature sensor, engine coolant temperature sensor (ECT) and the intake air temperature sensor (IAT) are thermistor circuits. When the sensors are cold, they have high resistance and high sensor voltage. As the temperature increases, this resistance and voltage decreases. The PCM supplies a five-volt signal to the sensors, 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 P0711 is set when the PCM/TC has completed two warm-up cycles with the following parameters detected:
^ Engine coolant below 30°C (80°F) after exceeding 71°C (160°F).
^ IAT and ECT within 6°C (10°F).
^ Transaxle fluid temperature reading is greater than 9°C (16°F) of the IAT during start-up.

IMPORTANT: The transaxle fluid temperature ECT and IAT sensors are continuously checked when ignition is On.

NOTICE: Visually inspect the transaxle fluid temperature, ECT and IAT wires for evidence of shorts to battery/ignition voltage. Shorts to battery/ignition voltage will skew the sensors resistance and cause DTC P0710 and P0711 to set.
