Intake Air System Leak
The Engine Control Module (ECM) has detected a vacuum leak into the engine. The ECM monitors the air passing through the Mass Air Flow (MAF) sensor, a vacuum leak means that unmetered air is entering the engine without passing through the MAF.
Cause:
Check for intake leaks
Faulty Mass Air Flow (MAF) sensor
Faulty PCV system
Symptoms:
Check engine light
