Manifold Absolute Pressure ( MAP )

MAP - Manifold Absolute Pressure


Graph of the MAP



Does the MAP sensor match the manufactures specifications, why or why not?

Yes it does match the manufactures specifications because I have same voltage which is 3.2volt.

Does a MAP sensor read vacuum or pressure?

The MAP sensor reads the vacuum.

Explain the internal operation of this sensor and why the output voltage changes.


It measures the variation of the intake manifold pressure and output voltage changes because the signal is going to the ECU. The increase and decrease of the voltage indicates the pressure in the intake manifold depending on the vehicles manufacturers specifications.
