What is the purpose and operation of the Positive Crankcase Ventilation (PCV) system and PCV Valve in a Honda Passport?

The Positive Crankcase Ventilation (PCV) system reduces emissions by circulating fresh air from the air cleaner through the crankcase, mixing with blow-by gases, and rerouting through a PCV valve to the intake manifold. The system includes a PCV valve, a fresh air inlet, and connecting hoses. The valve restricts flow to maintain idle quality when intake manifold vacuum is high. If abnormal conditions occur, the system allows excess blow-by gases to flow back into the air cleaner for normal combustion.
