Mazda CX-5 Service & Repair Manual: 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.

Air Fuel Ratio (A/F) Sensor
Purpose/Function
Detects the oxygen concentration (all-range air/fuel ratio) in the exhaust
gas as basic information for mainly determining the fuel injection amount.
