Transaxle Fluid Temperature (TFT) Sensor Inspection

WARNING: This page is about a different car, the 2005 Mazda MPV. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect the coupler component.
Remove the oil dipstick.
Insert the thermistor probe into the filler tube.
Start the engine.
