What is a PCV valve on the Dodge Caliber?

The PCV system outputs crankcase gases from the engine, reducing harmful emissions into the atmosphere. The gases that were drawn from the combustion chambers are routed through the PCV valve back into the inlet line.

The system consists of the PCV valve, a sealed filler cap, an air intake air inlet, and a set of vacuum hoses. It is recommended to replace the PCV valve at 96,000 km, 144,000 km, 192,000 km.

The original valve number is 05047 002AA.
