Mazda CX-5 Service & Repair Manual: Control Valve Body [Fw6 A EL, Fw6 Ax EL]
Purpose/Function
-
A direct linear solenoid has been adopted for the solenoid valve which contributes to improved shift response, drive feel and reduced shift shock by the improved precision of the hydraulic pressure control.
Construction
-
The control valve body consists of integrated hydraulic control related parts and electronic control related parts.
-
The transaxle range sensor, output shaft speed sensor, turbine/input shaft speed sensor, and the control valve body connector are built into the TCM and integrated with the automatic transaxle.
-
The transaxle fluid temperature (TFT) sensor, wiring harness, and the wiring harness cover bracket are built into the coupler component.
-
If any of the component parts of the control valve body has a malfunction, the control valve body must be replaced because the replacement of a single part is not possible except for the following parts:
-
On/off solenoid
-
Oil pressure switch A, oil pressure switch B
-
Coupler component (built into transaxle fluid temperature (TFT) sensor)

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 refriger ...
Engine Coolant Protection Inspection
1. Measure the engine coolant temperature and specific gravity using a thermometer
and a hydrometer.
CAUTION:
Use engine coolant at a concentration that meets the environmental conditions
in which the vehicle is driven, otherwise engine damage could occur.
The engine has alumi ...
Start Stop Unit Configuration (Using Read/Write Function)
NOTE:
When performing configuration, it is necessary to read the vehicle specification
information from the start stop unit before replacing it. Connect the M-MDS
to the vehicle and perform vehicle identification before removing the start
stop unit. The vehicle specification informa ...
