Fault text

Differential-pressure sensor, intake manifold: plausibility

Fault description

Differential Pressure Sensor Intake Manifold Pressure Too High (Bank 1)

Condition for fault identification

Test condition:

Differential pressure sensor monitor 6 % < Relative charge factor <120 %

-20?< Induction air temperature sensor < 85 锟斤拷C 560 rpm < Engine speed < 7200 rpm

Time after start > 30 sec. regardless of EVAP active/inactive

Terminal condition: Terminal 15, engine on Voltage condition:

Voltage in onboard electrical system >= 10 V

Condition for fault memory entry

0.2 sec.

Action in service

Visual inspection of vacuum sensor plug contacts

Check wiring between vacuum sensor and DME

Check induction system/crankcase for leaks (crankcase vacuum control can allow excess air from the crankcase to flow into the intake manifold, for instance, if vacuum line

from brake booster to vacuum pump is leaking)
