Barometric Pressure🔗

The barometric pressure (in kPa or psi).

  • If a dedicated barometric pressure sensor is installed and functioning correctly, this will be the reading from that sensor.
  • If no dedicated sensor is installed, this will be an estimate based on sampling the output of the manifold absolute pressure (MAP) sensor when the engine is below Engine Speed (RPM) Cranking Threshold.
  • If there is a fault detected with an installed sensor or with barometric pressure estimation, this will be the value specified in Barometric Pressure Default.
