Engine Emission Control: Notes
WARNING: This page is about a different car, the 2009 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Do not 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 includes the:
- EGR valve.
- EGR valve-to-intake manifold tube (2.3L).
- exhaust manifold-to-EGR valve tube (4.0L SOHC).
- EGR vacuum regulator solenoid.
- PCV valve.
