BAROMETRIC PRESSURE (BARO) SENSOR [SKYACTIV-G 2.5T]


id0140h0006000


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

amxuun00001414

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.

Fail-safe

DTC No.
