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.

What is the function of the PCV valve in the Honda Passport?

First of all, the Positive Crankcase Ventilation system takes the gases produced during combustion and sends them back to the intake manifold. The valve cover to the intake manifold hose contains a fresh air inlet hose and a PCV valve. If you pull the valve from the cover and no vacuum is present, check for a clogged hose or valve. Replace any damaged hoses. In case it does not rattle when shaken, replace the valve.
