Here are the definition of two sensor. Magkaiba po sila ng gamit para sa engine kaya be sure na map sensor ang kailangan nyo.

MAP sensor - Refers to a manifold absolute pressure sensor, a variable resistor used to monitor the difference in pressure between the intake manifold at outside atmosphere.
MAF sensor (mass air flow sensor) - A device used in many fuel injected engines to measure the amount of air entering the engine so the computer can control the air/fuel mixture. Located ahead of the throttle body, the MAF sensor uses a heated wire or filament to measure airflow.
