Mazda CX-5 Service & Repair Manual: Refrigerant Pressure Sensor [Manual Air Conditioner]
Purpose
-
The refrigerant pressure sensor detects the refrigerant pressure in the refrigerant cycle.
Function
-
The refrigerant pressure sensor converts the detected refrigerant pressure to an electric signal and sends it to the PCM.
Construction
-
The refrigerant pressure sensor is installed on the cooler pipe.
-
A capacitance type refrigerant pressure sensor, which converts refrigerant pressure into a linear electric signal, has been adopted.
-
Consists of a pressure detecting part and signal processing part.
-
The pressure detecting part is a variable capacity condenser, which changes capacitance according to the pressure.
-
The signal processing part detects the capacitance of pressure detecting part, converts it to voltage, then outputs it to the climate control unit.
Operation
Capacitance type
-
There is a clearance between the movable ceramic diaphragm and the ceramic base, and each side has an electrode.
-
When pressure is applied from the ceramic diaphragm side, the ceramic diaphragm deforms, and the clearance between the electrodes changes. As a result, capacitance is changed and pressure is detected.
Fail-safe
-
Function not equipped.

Shift Pressure Control (Line Pressure Control) [Fw6 A EL, Fw6 Ax EL]
Outline
The TCM drives the pressure control solenoid and adjusts the pressure based
on the accelerator pedal depression amount, vehicle speed, ATF temperature,
and gear shift signal. As a result, line pressure is controlled finely and with
high accuracy according to the engine load c ...

High Clutch [Fw6 A EL, Fw6 Ax EL]
Purpose/Function
The high clutch operates in 4GR, 5GR, and 6GR and intermittently operates
the rear carrier by drive force from the turbine shaft.
For the high clutch, a centrifugal balance clutch has been adopted to prevent
clutch drag and to assure stabilized piston thrust in ...
