The Tumble Control Valve (TCV) is built into the intake manifold. The Intake Air Control Valve Actuator (For Tumble Control Valve) is composed of a position sensor and a DC motor. The DC motor opens and closes the tumble control valve in response to signals from the Engine Control Module (ECM). The Tumble Control Valve Position Sensor is a non-contact type sensor. The position sensor measures the opening angle of the tumble control valve. The sensor is reliable and accurate, as it is electrically controlled by Hall-effect elements. The Diagnostic Trouble Code (DTC) will be set when the Tumble Control Valve Position Sensor output voltage flutters up and down beyond the normal operating range (less than 0.2 V, or higher than 4.8 V) for more than 0.5 seconds (open or short).
