DTC P0711 TRANSMISSION FLUID TEMPERATURE SENSOR "A" PERFORMANCE

description

2006 TRANSMISSION A750F Automatic Transaxle - Sequoia

The Automatic Transmission Fluid (ATF) temperature sensor converts the ATF temperature into a resistance value which is input into the ECM.

The ECM applies a voltage to the temperature sensor through ECM terminal THO1. The sensor resistance changes with the ATF temperature.

One terminal of the sensor is grounded so that the sensor resistance and voltage decrease as the temperature becomes higher.

The ECM calculates the ATF temperature based on the voltage signal.

DTC DETECTION CONDITION AND TROUBLE AREA REFERENCE

DTC No.

DTC Detection Condition

Trouble Area

P0711

Both (a) and (b) are detected. (2 trip detection logic)

a. Intake air and engine coolant temperatures are more than -10°C (14° F) at engine start.

b. After normal driving for over 22 minutes and 5.6 miles (9 km) or more, ATF temperature is less than 20°C (68°F).

No. 1 ATF temperature sensor

monitor description monitor description

This DTC indicates that there is a problem with output from the ATF temperature sensor and that the sensor itself is defective. The ATF temperature sensor converts the ATF temperature into an electrical resistance value. Based on the resistance, the ECM determines the ATF temperature and detects opens or shorts in the ATF temperature 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, and illuminates the MIL.
