TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR DESCRIPTION [JA5A-EL]

BME051719200T07

• The TFT sensor, which is installed in the transaxle case, detects the ATF temperature in the transaxle case, and sends the control signal to the TCM. The TCM controls the driving pattern and the torque converter clutch based on the signal from the TFT sensor.

Structure/Operation

• The TFT sensor is a thermistor type and the resistance changes according to the ATF temperature.

• The characteristic of the resistance is as shown in the figure below.

• The TFT sensor is integrated with the connector.
