Manifold Absolute Pressure Sensor

Manifold Absolute Pressure Sensor

The Manifold Absolute Pressure (MAP) sensor generates a signal that is proportional to the amount of vacuum in the intake manifold. The signal is sent to the Engine Control Module (ECM) and the information is used to control the air/fuel mixture ratio. Faulty MAP sensor can cause the engine to stall, surge or a rough idle.
