Intake Manifold Runner Control
(IMRC)Valve N316
The Intake Manifold Runner Control Valve N316 is
located on the variable intake manifold and is an
electro-pneumatic valve.
When it is activated, it operates the intake manifold
flap to change the length of the intake manifold.
Effects of Failure
If the valve fails, the intake manifold flaps are pulled
by a mechanical spring to an emergency running
position. This position corresponds to the power
setting of the intake manifold.
