Transmission Temperature Sensor/Switch: Description and Operation

Description

Transaxle Oil Temperature Sensor(OTS) monitors the automatic transaxle fluid's temperature and conveys the readings to Transaxle Control Module(TCM). It is an Negative n Thermal Coefficient(NTC) sensor whose resistance has an inversely proportional relationship with the temperature level. Data produced by this sensor is used to identify Damper Clutch (D/C) activation and deactivation zones within the low temperature and high temperature range and to compensate hydraulic pressure levels during gear changes.
