Instruments and Controls 5-13
For vehicles that have this gauge, it
is located near the instrument panel
cluster.
This gauge indicates vacuum during
light to moderate throttle and boost
under heavier throttle.
It displays the air pressure level in
the intake manifold before it enters
the engine's combustion chamber.
The gauge is automatically centered
at zero every time the engine is
started. Actual vacuum or boost
is displayed from this zero point.
Changes in ambient pressure,
such as driving in mountains and
changing weather, will slightly
change the zero reading.
