Emission Control System
The emission control system includes a Three Way
Catalytic Converter, Exhaust Gas Recirculation (EGR)
system, Positive Crankcase Ventilation (PCV) system
and Evaporative Emission (EVAP) control system.
The emission control system is designed to meet
federal and state emission standards.
Tailpipe Emission
1. Starting the engine and warm it up to normal
operating temperature (the cooling fan comes on)
by driving the car on the road.
2. Connect a tachometer.
3. Check idle speed and adjust the idle speed, if
necessary (see page 11-102).
4. Warm up and calibrate the CO meter according to the
meter manufacturer’s instructions.
5. Check idle CO with the headlights, heater blower, rear
window defogger, cooling fan, and air conditioner off.
CO meter should indicate 0.1 % maximum.
System Description
Do not smoke during this procedure. Keep
any open flame away from your work area.
