Mazda CX-5 Service & Repair Manual: Electric 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 electric 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 electric variable valve timing motor/driver..
4. Rotate the eccentric shaft of the electric variable valve timing actuator by hand and verify that it rotates smoothly.
-
If it does not rotate smoothly, replace the electric variable valve timing actuator..
NOTE:
-
Hook a finger onto the joint groove of the eccentric shaft to rotate the shaft easily.
-
The eccentric shaft stops rotating at the maximum retard position when it is rotated counterclockwise as viewed from the front, and at the maximum advance position when rotated clockwise.
-
The eccentric shaft rotates 15.8 turns from the maximum retard position to the maximum advance position.
5. Install in the reverse order of removal.

Tcs Control
Outline
The TCS control actuates torque reduction through engine control, as well
as using brake control to control traction.
NOTE:
Engine control: Engine output is lowered by fuel cut and ignition timing
control to reduce the traction, preventing driving wheel slip.

Hydraulic Pressure Control System Outline [Fw6 A EL, Fw6 Ax EL]
Outline
The hydraulic control mechanism consists of an oil cooler which maintains
the hydraulic pressure at the optimum temperature, a control valve body and
each shift valve which perform adjustment and circuit switching of the hydraulic
pressure based on the control content calcula ...
