Examination
Using a manual vacuum pump, create a vacuum in the inlet and check that the axis of the mechanism moves smoothly and the vacuum is maintained at the same level.
Standard data:
- At the beginning of the movement: approx. -8 kPa (-60 mmHg Art.)
- At the end of the movement: approx. -27 kPa (-200 mmHg Art.)
In the event of a malfunction, replace the intake manifold assembly, see Sec. Mechanical part of the engine.
