Mazda CX-5 Service & Repair Manual / HVAC / A/C / Sensors, Switches, Relays / Differential Oil Temperature Sensor

Purpose, Function

The differential oil temperature sensor detects the rear differential oil temperature based on the resistance of the thermistor, and inputs it to the AWD CM.

Construction

The differential oil temperature sensor is installed in the rear differential carrier.

Operation

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.
