BAROMETRIC PRESSURE (BARO) SENSOR CONSTRUCTION/OPERATION [13B-MSP]
id0140g1172900
x
The BARO sensor is integrated with PCM.
x
The piezoelectric element is enclosed in the
sensor and the electric potential difference
changes as the BARO drops. The output voltage
decreases as the BARO decreases.

x
Install the intake manifold.
x
The magneto resistance element, used for the
sensor, detects the APV fully-closed position and
sends a voltage signal to the PCM.
x
When the APV closes, the APV position sensor
outputs a voltage of 1.0 V or more.
