The MAP Sensor in Buick Enclave is an important apparatus of the car that measures positive air pressure that is getting into the intake manifold so that the engine control unit or ECU can calibrate the fuel. A critical role when it comes to the air-fuel mixture for combustion especially in the speed-density method of fuel metering. While naturally aspirated engines of the Buick Enclave may employ either a MAP sensor or a mass airflow (MAF) sensor, those of a forced induction engine will require both. The MAP acts as an OBD II system and is involved in fuel delivery, ignition timing, and other factors that are related to the correct measurement of the air mass.
