Description & Operation: Description

• The sensor used is a thermistor (NTC) (A) in which resistance changes with temperature variation.
• When the TCM supplies about 5 V of power to the sensor, the sensor output value changes depending on ATF temperature.
• Oil temperature sensor is installed on the valve body and is integrated with E module.

Function 

• Automatic 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.
