BAROMETRIC PRESSURE (BARO) SENSOR [SKYACTIV-G 2.0]

Purpose

• Detects the barometric pressure as basic information for mainly determining the fuel injection amount.

Function

• Barometric pressure is detected by the PCM internally.

  BARO sensor characteristic

  

Construction

• The BARO sensor is integrated with the PCM.

• A piezoelectric element has been adopted for the detection part of the BARO sensor.

• A piezoelectric element produces voltage by the application of vibration or pressure. It detects barometric pressure as voltage using this character.

  

Operation

• The BARO sensor outputs the voltage value according to the barometric pressure and the barometric pressure is detected by the PCM internally.
