Is a MAP sensor necessary?
In modern vehicles, a computer and a series of sensors control the engine’s fuel consumption and other operations. While you may never have to work on any of these sensors yourself, one in particular is essential to a smoothly running engine — the MAP (manifold absolute pressure) sensor.
What happens if you disconnect MAP sensor?
Disconnecting the MAP or BARO sensor will set code 22. Misconnecting the BARO sensor to vaccum on a Mass Air car will cause the computer to lean out the fuel mixutre. Code 22 or 126 MAP (vacuum) or BARO signal out of range.

What happens when the MAP sensor goes bad?
When the driver uses the engine to brake, pressure can go as low as 10 in. Hg. Upon accelerating, however, the open throttle body allows air to rush in faster, increasing pressure in the intake. At wide-open throttle, intake and atmospheric pressure are nearly equal. MAP sensor problems could trigger a DTC and check engine light.

How is a MAP sensor connected to the intake manifold?
