Engine Emission Control: Notes
WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Do not permanently remove any part of the engine emission control system. Operating the engine without the engine emission control system intact will reduce fuel economy and engine ventilation. This will weaken engine performance and shorten engine life.
The engine emission control system consists of the:
- Positive crankcase ventilation (PCV) system.
- Exhaust gas recirculation (EGR) system.
