Barometric Pressure Sensor

WARNING: This page is about a different variant/trim than selected.

The barometric pressure sensor is placed at intake manifold collector. It detects intake manifold pressure and sends the voltage signal to the ECM. The sensor uses a silicon diaphragm which is sensitive to the change in pressure. As the pressure increases, the voltage rises.
