1 Bolt

2 Camshaft Actuator

3 Bolt
When the engine is running, the camshaft actuator rotates the intake camshaft hydraulically and mechanically
relative to the camshaft sprocket by 32° crank angle to the "advanced" position and back to the "retard"
position.
The camshaft actuator is actuated electro-mechanically by the Engine Control Module (ECM).
The positioning time of apporx. 1 second is dependent on the engine oil pressure at the camshaft actuator and on
the oil viscosity and oil temperature, respectively.
The camshaft indicator on the camshaft sprocket provides the camshaft rotational speed to the position sensor
as an input parameter for the engine ignition control unit.
