Mazda CX-5 Service & Repair Manual: Hydraulic Variable Valve Timing Actuator Inspection
WARNING:
-
A hot engine can cause severe burns. Turn off the engine and wait until it is cool before servicing.
CAUTION:
-
Do not disassemble the hydraulic variable valve timing actuator because it is a precision unit.
1. Disconnect the negative battery cable..
2. Remove the plug hole plate..
3. Remove the ignition coil/ion sensors..
4. Remove the cylinder head cover..
5. Verify that the notch of the rotor and projection of the cover on the hydraulic variable valve timing actuator are aligned and fitted.
-
If the notch of the rotor and projection of the cover are not aligned, rotate the crankshaft in the direction the engine rotates two turns and verify that they are aligned.
-
If the notch of the rotor and projection of the cover are still not aligned, replace the hydraulic variable valve timing actuator..
-
If, when turning the crankshaft, there is a slapping noise from the hydraulic variable valve timing actuator each time before the cam reaches its maximum lift, it means that the actuator is not secured. Replace the hydraulic variable valve timing actuator..
6. Install in the reverse order of removal.

Control Valve Body [Fw6 A EL, Fw6 Ax EL]
Purpose/Function
The control valve body controls the hydraulic pressure generated by the oil
pump by each solenoid valve. In addition, the oil passages which introduce hydraulic
pressure to the pistons for each clutch and brake is formed by the switching
of each built-in shift valve. ...

Body Measurements
Before removal or rough?cutting, first measure the body at and around the
damaged area against the standard reference dimension specifications. If there
is deformation, use frame repair equipment to make a rough correction.
