It&rsquo;s used by the PCM to monitor engine load. It converts engine vacuum into an electrical signal that is sent to the PCM. As your car accelerates under load, the engine vacuum also drops. A drop in engine vacuum means that the absolute pressure in the intake manifold has increased.<\/p>\n\n\n\n<p>Vehicle engines may also come equipped with a <a href=\"https:\/\/www.carparts.com\/barometric-pressure-sensor\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"barometric pressure sensor\">barometric pressure sensor<\/a>. This sensor detects subtle changes in atmospheric air pressure. It then converts this signal to an electrical signal that is sent to the PCM for interpretation.<\/p>\n\n\n\n<p>In most cases, the MAP sensor and BARO sensor are contained within the same housing. The <a href=\"https:\/\/www.carparts.com\/blog\/is-it-safe-to-drive-with-a-bad-map-sensor\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"MAP sensor\">MAP sensor<\/a> is connected to manifold vacuum, while the BARO sensor is vented to the atmosphere. However, there are some vehicles where the MAP sensor and BARO sensor are stand-alone components.<\/p>\n\n\n\n<p>Input from these sensors and other crucial sensors, such as the mass airflow sensor and throttle position sensor, is used by the PCM to monitor load and altitude.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">More About MAF and BARO<\/h3>\n\n\n\n<p>On some Mass Airflow (MAF) systems, the <a href=\"https:\/\/www.carparts.com\/mass-air-flow-sensor\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"MAF sensor\">MAF sensor<\/a> also measures barometric pressure, but some have a separate MAP sensor that measures manifold pressure and barometric pressure.
