Mazda CX-5 Service & Repair Manual: Oil Pump [Fw6 A EL, Fw6 Ax EL]
Purpose/Function
-
The oil pump generates hydraulic pressure in the oil line of the automatic transaxle together with supplying lubrication to powertrain related parts.
Construction
-
The oil pump has adopted a gear type with built-in outer and inner rotors.
-
The inner rotor engages with the torque converter and rotates in conjunction with the rotation of the torque converter.
Operation
-
When the inner rotor in the oil pump rotates, vacuum is generated in the outer rotor. As a result, ATF in the oil pan is suctioned to the oil pump. Further rotation of the inner rotor causes the inner rotor blades to push the ATF and discharge it from the oil pump.
-
The ATF discharge flow amount increases or decreases in proportion to the rotation speed of the inner rotor.

WARNING:
Hot engines and engine oil can cause severe burns. Turn off the engine and
wait until it and the engine oil have cooled.

Power Metal Oxide Semiconductor Field Effect Transistor (Power Mos Fet) [Full
Auto Air Conditioner]
Purpose
The power MOS FET controls the blower motor rotation speed.
Function
The power MOS FET controls the supply voltage to the blower motor based on
the gate voltage sent from the climate control unit, and adjusts the fan rotation
speed (airflow volume).

WARNING:
Never remove the cooling system cap or loosen the radiator drain plug while
the engine is running, or when the engine and radiator are hot. Scalding engine
coolant and steam may shoot out and cause serious injury. It may also damage
the engine and cooling system.
