DTC P0710 Transmission Fluid Temperature Sensor "A" Circuit

CIRCUIT DESCRIPTION

DTC Detecting Condition:

The ATF temperature sensor converts fluid temperature into a resistance value which is input into the ECM.

MONITOR DESCRIPTION

Monitor Strategy:

Typical Enabling Conditions:

Typical Malfunction Thresholds:

Component Operating Range:

The automatic transmission fluid (ATF) temperature sensor converts ATF temperature to an electrical resistance value. Based on the resistance, the ECM determines the ATF temperature, and the ECM detects an opens or shorts in the ATF temperature circuit. If the resistance value of the ATF temperature is less than 79 Ohms*1 or more than 156 k Ohms*2, the ECM interprets this as a fault in the ATF sensor or wiring. The ECM will turn on the MIL and store the DTC.

*1: 150°C (302°F) or more is indicated regardless of the actual ATF temperature.
*2: -40°C (-40°F) is indicated regardless of the actual ATF temperature.

HINT: The ATF temperature can be checked on the OBD II scan tool or hand-held tester display.
