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.

Heated Oxygen Sensor (HO2 S) Heater Control
Outline
Based on the control of the HO2S heater, a stabilized oxygen concentration
is detected even at low exhaust temperatures, and feedback control of fuel injection
even at cold engine start is made possible for improved cold temperature exhaust
emission performance.
