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

Oil Pump
Outline
The oil pump has a mechanism for feedback control of oil pressure. As a result,
an oil pressure increase of more than the set pressure is suppressed and oil

No.2 Removal/Installation
NOTE:
Because the IAT sensor No.2 is integrated in the MAP sensor, replacing the
IAT sensor No.2 includes replacement of the MAP sensor/IAT sensor No.2.
1. Disconnect the negative battery cable..
2. Disconnect the MAP sensor/IAT sensor No.2 connector.
3. Remove the MAP sensor/IA ...
Fuel Pump Control
Outline
By switching the fuel pump discharge amount, reduced power consumption and
improved fuel economy have been realized.
The PCM determines the optimum fuel pump drive force according to the engine
operation conditions, and sends the fuel pump drive signal to the fuel pump

Money-Saving Suggestions
How you operate your Mazda determines how far it will travel on a tank of fuel.
Use these suggestions to help save money on fuel and repairs.
• Avoid long warm-ups. Once the engine
runs smoothly, begin driving.
• Avoid fast starts.
• Keep the engine tuned. Follow the maintenance
