A manifold absolute pressure sensor (MAP sensor) measures the pressure in the intake manifold, calculating the amount of air entering the engine and sending the corresponding voltage signal to the engine control module (ECM). The ECM uses this information to adjust the fuel injection pulse width and timing. When the MAP sensor is not functioning correctly, the ECM may not be able to determine the engine's airload accurately, which may cause a poor air-fuel mixture. Symptoms of a failing MAP sensor include reduced fuel efficiency, engine hesitation, and inoperable mass airflow sensor.
