Boost Pressure (HPA)

Measurement range: 0-2550 hPA.

The value is calculated from the boost pressure. It indicates the pressure in the intake system downstream of the turbocharger (TC).

The engine control module (ECM) calculates the boost pressure from the boost pressure sensor. The pressure is relative to atmospheric pressure.
