An actuator for an intake manifold tuning valve to regulate airflow in an intake manifold of an internal combustion engine. The actuator includes a motor, control circuit, and sensor all mounted in a housing that has an opening through which an output shaft extends. The output shaft carries a valve blade that is positioned within the intake manifold when the actuator is assembled in place. The sensor provides the control circuit with feedback data indicating the position of the valve blade and this data permits the actuator itself to provide closed loop control of the position of the valve blade using an actuator command received from the engine's electronic control unit. The housing includes a stop member that engages the valve blade at a certain rotational position to thereby enable diagnostic checks of the valve to determine if the blade is present and functioning.
