Location 

The pressure sensor is located at the top on the left cylinder head.

task 

The pressure sensor detects the absolute pressure in the suction pipe.

The intake manifold pressure is used to detect the air mass when starting the engine. When the engine has started, the signal from the hot film MAF sensor is monitored.

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 intake manifold for the ME control unit.
