Temperature Sensor "A" Performance; 2015 MY Tundra [08/2014 - ]
DTC
P0711
Transmission Fluid Temperature Sensor "A" Performance
DESCRIPTION
The ATF temperature sensor converts the fluid temperature into a resistance value for use by the ECM.
resistance decreases.
The ECM calculates the fluid temperature based on the voltage signal.

DTC DETECTION CONDITION
TROUBLE AREA
P0711
Either condition is met (2-trip detection logic):
(a) Certain monitor enabling conditions are met and the ATF
temperature is below 20°C (68°F).
(b) Certain monitor enabling conditions are met and the ATF
temperature is 110°C (230°F) or higher.
Transmission wire (No. 1 ATF
temperature sensor)
MONITOR DESCRIPTION
This DTC indicates that there is a problem with output from the Automatic Transmission Fluid (ATF) temperature
sensor and that the sensor itself is defective. 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 sensor circuit or a fault in 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, turns on the
MIL and stores the DTC.
When the ATF temperature is 110°C (230°F) or more and the engine coolant temperature takes 10 seconds or
more to reach 60°C (140°F) after a cold start, the ECM also determines this as a fault, turns on the MIL and
stores the DTC.
