Oil Temperature Sensor
Function
The oil temperature sensor is installed in hydraulic control unit and is connected in series with the starter lock-out
contact.
This means that the temperature signal is transferred to TCU when the starter lock-out contact is closed.
The oil temperature has a considerable effect on the shifting time and therefore the shift quality. By measuring the oil
temperature, shift operations can be optimized in all temperature ranges.
