CIRCUIT DESCRIPTION
The VVT system controls the intake camshaft to provide the optimal valve timing for every driving condition. This control
is performed based on the signals, such conditions as intake air volume, throttle position and engine coolant tempera-
ture.
The ECM controls the oil control valve (OCV), based on the signals output from the sensors. The VVT controller regu-
lates the intake camshaft angle using oil pressure through the oil control valve (OCV). As result, the relative position
between the camshaft and the crankshaft becomes optimal, and the engine torque improves, fuel economy improves,
exhaust emissions decrease under overall driving conditions. Also, the ECM detects the actual valve timing using the
signals from the camshaft position sensor and the crankshaft position sensor, and performs feedback control. This is
how target valve timing is achieved by the ECM.
