Due to the clean design of Chevrolet Corvette, the MAP Sensor plays a very important role of measuring the air pressure that is positive in the intake manifold and relaying this information to the engine control unit to balance the fuel injection. MAP Sensor is a very vital component in fuel-injected engines and, in speed-density method, it has the responsibility of setting the air-fuel mixture for the combustion process. Naturally aspirated engines might use, for instance, a MAP sensor or a mass airflow sensor, while forced induction engines will employ the two. The MAP Sensor also helps in the on board diagnostic and exhaust gas recirculation valve and is useful in providing accurate measurements required for metering of fuel and optimal engine performance.
