  Barometric pressure sensor position   GF07.04-P-5040-01GS 
  Barometric pressure sensor task Detecting the ambient pressure. The pressure information is required for: Altitude recognition for starting mixture enrichment  
  Barometric pressure sensor function The pressure in the intake manifold alters the shape of a diaphragm and the piezo resistors alter their resistance. This influences the output voltage which is used by the ME control module as information regarding the ambient pressure.
