Variable Valve Timing Actuator: Description and Operation
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 and exhaust valves can be changed to match the camshaft. Engine performance can be increased, idle quality increased and emissions reduced by
regulating the camshaft timing changes.
There are diagnostics for this function.
