The Barometric Pressure Sensor (BARO sensor) is mounted to the sensor bracket at the rear of the cylinder block just above the flywheel housing. The sensor sends an electrical signal to the ECM indicating barometric pressure. It is electrically connected to the ECM through the engine sensor wire harness. A hose is attached to the inlet of the sensor to protect it form dirt and prevent plugging. The ECM uses the data in controlling fuel delivery to the engine.
