Fault text
Air-mass system
Fault description
Mass or Volume Air Flow Too High
Condition for fault identification
Test condition:
Mass airflow data monitor
6 % < relative charge <120 %
-20?< induction air temperature < 85 掳C
560 1 rpm < engine speed 30 sec.
Regardless of whether EVAP is active/inactive
Terminal condition: Terminal 15, engine on
Voltage condition:
227
Voltage in onboard electrical system >= 10 V
Condition for fault memory entry
0.2 sec.
Action in service
1) Visual inspection of HFM plug contacts
2) Check wiring between HFM and DME
3) Check induction system/crankcase for leaks (the positive
crankcase ventilation system can allow vacuum leaks with
air from the crankcase entering the manifold, for instance, if
vacuum line from brake booster to vacuum pump is leaking)
4) Check for DISA diagnostic fault code entries and DISA
control operation (DISA fault does not prevent HFM
plausibility check)
5) Carry out VVT travel limit initialization routine
