The sensor is mounted either on the bulkhead, air
cleaner, throttle body or elsewhere in the engine
compartment. A vacuum hose connects the sensor
to a strong source of manifold vacuum. (Some new
MAP sensor types may be directly mounted to the
manifold, eliminating the vacuum hose connection.)
The BARO sensors are vented to the atmosphere -
there is no vacuum hose attached.
Some Honda engines locate the MAP sensor inside
a control box containing several vacuum hoses and
solenoids.
