  Pressure sensor, location   GF07.04-P-5014-01HA 
  Pressure sensor, task Detecting the absolute pressure (boost pressure) in the intake manifold. The ME control unit needs the boost pressure and the charge air temperature for the calculation of the supplied air mass. The required quantity of fuel for the particular operating conditions is calculated on the basis of a performance map stored in the ME control unit.  
  Pressure sensor, design   GF07.04-P-5014-03HA 
  Pressure sensor, function The intake manifold pressure distorts a diaphragm which has an effect on the piezo resistor. This alters the resistance value of the piezo resistor and influences the output voltage, which is used as information regarding the boost pressure for the ME control unit. The pressure gauge range is between 0.2 up to 2.5 bar.
