Description and operation
| Description |
| • |
The sensor used is a thermistor (NTC) in which resistance changes with temperature variation. |
| • |
Oil temperature sensor is installed on the valve body integrated with a main 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. |
