DTC P0711 Transmission Fluid Temperature Sensor ”A”
Performance
CIRCUIT DESCRIPTION
The ATF temperature sensor converts fluid temperature into a resistance value which is input into the ECM.
DTC No. DTC Detecting Condition Trouble Area
P0711
Both (a) and (b) is detected. (2 − trip detection logic)
(a) After 12 seconds of the engine start, the temp. of the atmo-
sphere and that of the engine coolant is more than
− 10 ° C.
(b) After a normal driving for over 18 minutes and 20 seconds
and 9 km (6 miles), the ATF temp. is less than 20
° C.

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 open or short 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 20
_ C (68 _ F) 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 110
_ C (230 _ F) or more after 18 minutes of engine cold start, the ECM also
determines this as a fault, turns on the MIL, and stores the DTC.
