Transaxle Fluid Temperature Sensor
WARNING: This page is about a different car, the 2002 Mazda 626 and 2001 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.
Transaxle Fluid Temperature (TFT) sensor is located on the solenoid valve body. The PCM monitors voltage across the TFT sensor thermistor to determine transaxle fluid temperature. Depending on temperature, the PCM controls line pressure, shift scheduling and TCC operation. Malfunction of sensor will cause incorrect line pressure and possible lack of TCC operation.
