2019 BMW 128i Convertible (E88) L6-3.0L (N51) A L L Diagnostic Trouble Codes ( DTC ): Manufacturer Code Charts Page 205
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
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)
