Question

Quizplus · Accepted Answer

The Positive Crankcase Ventilation (PCV) system is typically not directly controlled by the Powertrain Control Module (PCM). The PCV system is a passive system that regulates crankcase pressure and recycles crankcase gases without direct electronic control from the PCM, unlike the EGR, EVAP, and AIR systems which are actively managed by the PCM to control emissions.
