Manifold Absolute Pressure Sensor
The manifold absolute pressure sensor (MAP sensor) works with intake air pressure to define proper air and fuel quantities required for the ignition cylinders. The MAP sensor measures the vacuum of the intake manifold, which fluctuates according to engine load, relative to the barometric pressure.
