Positive Crankcase Ventilation (PCV) System: Overview
WARNING: This page is about a different variant/trim than selected.
CAUTION:
Do not remove the PCV system from the engine. Removal of the PCV system adversely affects the fuel economy and engine ventilation and results in shorter engine life.
The PCV system cycles crankcase gases back through the induction system into the engine where they are burned. The PCV valve regulates the amount of ventilated air and blow-by gases to the intake manifold.
The Escape Hybrid uses a non-heated PCV system. PCV systems that comply with OBD PCV monitoring requirements will use a quarter-turn camlock thread design at one end to prevent accidental disconnection from the valve cover. For more information about the PCV monitor refer to POSITIVE CRANKCASE VENTILATION (PCV) SYSTEM MONITOR .
