DTC P0711 Transmission Fluid Temperature Sensor ºAº
Performance
CIRCUIT DESCRIPTION
The ATF temperature sensor converts fluid temperature into a resistance value which is input into the ECM.
DTC No.DTC Detecting ConditionTrouble Area
P0711
(A) Both (a) and (b) are detected: (2-trip detection logic)
(a) Intake air and engine coolant temps. are more than -10°C
(14°F) at engine start
(b) After normal driving for over 20 min. and 9 km (6 mile) or
more, ATF temp. is less than 20°C (68°F)
(B) After 17 min. of engine start, the ATF temp. is 110°C
(230°F) or more (2-trip detection logic).

MONITOR DESCRIPTION
The ATF temperature sensor converts the ATF temperature to an electrical resistance value. Based on the
resistance, the ECM determines the ATF temperature and detects an opens or shorts in the ATF temperature
circuit or a fault of the ATF temperature sensor.
After running the vehicle for a certain period, the ATF temperature should increase. If the ATF temperature
is below 10C (50F) after running the vehicle for a certain period, the ECM interprets this as a fault, and
turns on the MIL.
When the ATF temperature is 110C (230F) or more after 17 minutes of engine cold start, the ECM also
determines this as a fault, turns on the MIL, and stores the DTC.
