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 掳C

560 rpm < Engine speed 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

1) Visual inspection of vacuum sensor plug contacts

2) Check wiring between vacuum sensor and DME

3) 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)
