Kia Sportage: Automatic Transaxle Control System / Transaxle Oil Temperature Sensor Description and operation

Description

•	The sensor used is a thermistor (NTC) in which resistance changes with temperature variation.

•	The TCM supplies about 5 voltage to the sensor; the output value changes with ATF temperature.

•	Oil temperature sensor is installed on the valve body integrated with a solenoid valve harness.

Functions

•	Transaxle oil temperature sensor monitors the temperature of ATF and conveys the readings to TCM.

•	Data produced by this sensor is used to identify torque converter clutch activation and deactivation zones within the low temperature and high temperature range and to compensate hydraulic pressure levels during gear changes.
