task	Detecting the absolute pressure in the intake manifold. The pressure information is required: Functional chain test OBD and EURO3/4 (e.g. camshaft adjustment, exhaust gas recirculation or leak tightness of evaporative emission control system) ME2.8: altitude detection for start enrichment Engine 113.960 with code 479: testing the cylinder shut-off
Body	see Fig.
Function	The pressure in the intake manifold alters the shape of a diaphragm and the piezo resistors alter their resistance. The output voltage which is influenced in this way serves as information to the control module ME about the pressure in the intake manifold.
