DESCRIPTION AND OPERATION
Engine Emission Control
CAUTION: Do not remove any part of the engine emission control system. Operating the
engine without the engine emission control system will reduce fuel economy and engine
ventilation. This will weaken engine performance and shorten engine life.
The engine emission control consists of the:
zpositive crankcase ventilation (PCV) system.
z exhaust gas recirculation (EGR) system.
Typical Vehicle Emission Control Information (VECI) Decal
The Vehicle Emission Control Information (VECI) decal shows:
zthe components of the emission control system.
z the correct vacuum hose routing.
