MAP Sensor in Chevrolet Astro is among the crucial parts of the car with a function of measuring positive air pressure on the intake manifold. This small device sends information to the engine control unit (ECU), to enable it to regulate the fuel injectors based on the volume of air in the cylinders in order to optimize air-fuel mixture for combustion. It is very possible that Chevrolet Astro may have different types of MAP Sensors especially on naturally aspirated engines and forced induction engines. Whereas, the naturally aspirated engine may use only a MAP Sensor or mass airflow (MAF) Sensor, the forced-induction engines use both for the premier results. The MAP Sensor plays an important role in the drivers metering of fuel and the engine's ignition system, as well as monitoring its efficiency, placing it among the vehicle's electronic control systems.
