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.

Honda Passport PCV Valve

PCV Valve is one of the most significant features that assist in managing emission on the journey and boosting the performance of the Honda Passport engine. Through returning the combustion by product gases in the crankcase evenly into the engine detonating chambers through the PCV Valve, the harm to the environment and the formation of sludge and other substances detrimental to the engine is avoided. Depending on intake manifold vacuum conditions, the functions of PCV Valve limit the intake of gas at idle when the engine may become too lean, and at higher rpm or under load, allows more gases to enter. Moreover, the PCV Valve will in equal measure perform a function of a flame arrester and assist in ensuring that there is sufficient fresh air into the crank case, provided that it is not positive pressure. As a result, the continuous usage of the PCV Valve in maintaining a good function of the vehicle's engine by preventing blockage of oil, oil leaks, and high fuel consumption is proficient.
