The DM (diagnostic module) pressure sensor (B5/2) is located on the left wheelhousing at the component compartment wall. The sensor converts
pressure values into voltage signals and transmits those to the diagnostic module. Pressure changes are recognized very quickly (approximately 5
milliseconds).
The DM pressure sensor (B5/2) measures either the absolute pressure in the intake manifold or, if the purge-flow switchover valve (Y27/6) is
activated, the pressure in the line between the charcoal canister and the purge control valve (Y58/1).
