Variable Valve Timing Actuator Inspection
VARIABLE VALVE TIMING ACTUATOR INSPECTION
Caution
^
The variable valve timing actuator cannot be disassembled because it is a precision unit.
1. Remove the cylinder head cover.
2. Confirm that the key groove on the rotor and the timing mark on the sprocket of the variable valve timing actuator are aligned and fitted.
^
If the key groove and the timing mark are not aligned, rotate the crankshaft clockwise one rotation and then counterclockwise one rotation.
Verify that the key groove and the timing mark are aligned.
^
If the key groove and timing mark are still not aligned, replace the variable valve timing
^
If, when rotating the crankshaft, there is a hitting noise from the variable valve timing actuator each time the cam passes the fully lifted
position, it means that the actuator is not secured. Replace the actuator.
3. Install the cylinder head cover.
