Differential Oil Temperature Sensor Construction/Operation - Mazda CX-9 2007 Service Highlights

DIFFERENTIAL OIL TEMPERATURE SENSOR CONSTRUCTION/OPERATION

• The differential oil temperature sensor is installed in the rear differential carrier.
• The differential oil temperature sensor uses a thermistor whose resistance changes according to changes in
the rear differential oil temperature.
• The resistance grows smaller as the oil temperature rises and vice-versa, as shown.
