Variable Valve Timing Actuator: Testing and Inspection

VARIABLE VALVE TIMING ACTUATOR INSPECTION

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.
