Intake air pressure and temperature: two different quantities

Useful to know

The Bosch combined sensor measures air pressure and temperature in the intake tract. Pressure is read through a sensitive element, and temperature is read through an NTC resistor. The solution is used in various engine configurations. [1]

These two quantities are not the same as a directly measured mass flow from a flow meter. In diagnostic data, always look at the name and unit: a pressure value cannot be compared as a number with a mass value per unit of time.

The "boost sensor" designation is not enough to determine the exact part for each car. The installation location, scope and connection to the control unit are product features. When checking an abnormal reading, the operating state of the engine should also be considered, instead of declaring one value to be universally normal.
