Kia Optima Hybrid (TF HEV) 2016-2020 Service Manual / Automatic Transaxle System / Automatic Transaxle Control System / Transaxle Oil Temperature Sensor Description and Operation

Description

Transaxle oil temperature sensor monitors the automatic transaxle fluid''s temperature and conveys the readings to TCM. It is an NTC (Negative Thermal Coefficient) sensor whose resistance has an inversely proportional relationship with the temperature level. Data produced by this sensor is used to identify clutch activation and deactivation zones within the low temperature and high temperature range and to compensate hydraulic pressure levels during gear changes.
