Camshaft Control (CVVT)




Camshaft Control (CVVT)







When the camshaft (A) is set at the factory, it is aligned with the position of the crankshaft (B). The position of the camshaft in relation to the crankshaft is designated the camshaft 0 position. During camshaft (CVVT) control, the 0 position of the camshaft is advanced so that the opening and closing of the intake valves can be changed to relative to the camshaft. By controlling the camshaft (the camshaft is regulated from its 0 position) the performance of the engine is increased, the idle speed quality is improved and the emissions are reduced.

There are diagnostics for this function.
