Variable Valve Timing Actuator Inspection

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2008 Mazda 6, 2007 Mazda 6, 2006 Mazda 6, 2005 Mazda 6, and 2004 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
The variable valve timing actuator cannot be disassembled because it is a precision unit.
  1. Confirm that the key groove of the rotor and the timing mark of the sprocket at the variable valve timing actuator are aligned and fitted.
    • If the timing mark and the key groove are not aligned, rotate the rotor toward the bulb timing retard position by hand until they are in place.
    • If the rotor and sprocket are not secured even though their timing mark and the key groove are aligned, replace the variable valve timing actuator.
