Is a map sensor the same as a mass airflow sensor?

No, a map (Manifold Absolute Pressure) sensor and a mass airflow (MAF) sensor are not the same, although both are used in an engine's air management system. The MAP sensor measures the pressure within the intake manifold to help determine engine load, while the MAF sensor measures the amount of air entering the engine to calculate the correct fuel-to-air ratio. Each sensor serves a distinct purpose and provides different information to the engine control unit (ECU) for optimal performance.
